The Complete Guide to Asphalt Paving for Roads, Parking Areas and Villa Yards

What asphalt paving is and why it matters

Asphalt paving is the construction of a flexible pavement made of successive layers, finished with a hot asphalt mix that is spread and compacted by machines. Its purpose is to turn a shifting earth surface into a stable, clean surface that carries cars and trucks and sends rainwater away from the building.

Many owners think of asphalt as a single layer. In reality, the black surface you see is only the last part of a long piece of work carried out below it. The strength of a road comes from the compacted soil and the granular fill layers well before it comes from the asphalt itself. This is why some new roads crack or settle soon after they are opened. The work underneath was not done as it should have been.

What correct asphalt paving gives you

• A stable surface that does not turn to dust in the wind or to mud in the rain.
• Comfortable driving, with less wear on tyres and suspension.
• Organised drainage that protects the foundations of the building and the boundary walls.
• A tidy appearance that adds to the value of a villa or a commercial complex.
• Maintenance that is easier and more economical than most other paving types, provided the work is done properly.

Start below the surface

If you own open land around a villa, a compound or a warehouse, asphalt is often one of the quickest ways to turn it into space you can use every day. Cars can park, trucks can turn, and visitors arrive at a clean entrance instead of a dusty yard.

The important thing is to understand what happens under the surface before you ask about how it will look. The colour and smoothness on handover day tell you very little. What decides whether the asphalt will last is the preparation of the soil, the quality and thickness of the fill layers, the compaction of each stage and the way water is directed off the surface. The rest of this guide walks through each of these points in order, so that you can discuss your project with any contractor on an equal footing and know which questions to ask.

Where asphalt is used and how the use changes the design

The way asphalt is built changes with the location and with the kind of traffic the surface will carry. A villa yard should not be built to the same specification as a road that trucks use every day, and the reverse is also true. Over-designing wastes money, and under-designing leads to early failure.

Villa and palace yards

Traffic here is usually light and limited to the family cars. The yard still needs particular care with levels, because it sits right next to the building. A small error in the falls can direct water towards the walls or the entrance. Owners also care about appearance, smoothness and straight edges where the asphalt meets kerbs and pavements.

Parking areas for compounds and shops

Parking areas face turning traffic and frequent stopping. A car that turns its wheels while standing still loads the surface in a very different way from a car passing at speed. This is why parking areas need stronger layers and a clear plan for aisles and bays.

Internal roads and new subdivisions

Streets in new land subdivisions and internal roads in residential compounds carry mixed traffic, including delivery vehicles and construction equipment while the plots are being built. These roads need a layer design based on the expected load, and coordination with water and drainage networks before any asphalt is laid.

Warehouses and industrial yards

This is where the heaviest loads are. Trucks and forklifts press hard on the surface. Thicknesses and layers are chosen after a careful survey of the vehicle types and how often they will pass. In some cases concrete paving is a better choice for particular parts of the yard, such as loading areas.

Why we ask this question first

Defining the use from the start is the first thing we ask about in the asphalt service at Yam Integrated Construction, because every later decision depends on it. The number of layers, their thickness, the type of mix, the size of the equipment and even the drainage plan all follow from who and what will use the surface. When you contact a contractor, describe the vehicles you expect clearly. Mention any future plans as well, such as a parking shade, a delivery entrance or a change in how the land will be used, because these change the design too. You can read more about our approach on the asphalt and road paving service page.

Site and soil survey before the design

Every asphalt design starts with the ground that is actually there. Many settlement and cracking problems happen because nobody looked seriously at the soil before deciding on the layers. An early survey costs little compared with redoing the work.

What the survey looks at

• Soil type. Whether it is sandy, clayey, rocky or mixed. Clay swells with water and shrinks as it dries, so it needs special treatment.
• Previous fill. Some plots were filled with construction waste or with loose soil during building works. These materials settle later if they stay under the asphalt.
• Ground levels. And how they relate to the public street, the building and the places where water enters the site.
• Groundwater and moisture. Especially on coastal and low-lying sites.
• Buried services. Such as water, sewer and power lines, so they are not damaged during excavation and compaction.
• Trees and roots. Roots close to the paving lift the asphalt over time.

Cases that need extra care

On some sites near the eastern coast, salty sabkha soil appears. This soil becomes weak when saturated and needs removal or treatment, together with separating layers, before work begins. On open desert sites, wind moves the sand and piles it along the edges, so the design should make cleaning easy. In mountain areas, rock can appear at different depths within the same plot, which calls for careful levelling.

When laboratory tests are needed

For small yards, a field inspection and the engineer's experience, together with compaction tests during the work, may be enough. For internal roads, large parking areas and industrial yards, it is better to take soil samples to find out how much load the ground can carry. The results of these tests then set the layer thicknesses instead of an estimate.

Record what the team found

Ask the contractor what was found during the survey and request that the soil notes are written into the quotation. If unexpected materials then appear during excavation, there is a clear basis for dealing with them without disagreement. Site preparation often begins with digging out weak material and backfilling in layers, and you can learn more about that work on our excavation and backfilling page.

Pavement layers from the ground up

An asphalt pavement works much like a building. Each layer carries the one above it and spreads the load over a wider area, so that by the time the pressure reaches the soil it is much lower. If one layer is weak, it shows on the surface however good the asphalt is.

1. Natural subgrade. This is the real foundation. It is cleared of debris and organic matter, then levelled, watered and compacted until it reaches the required density.
2. Subbase. A layer of selected fill spread over the compacted subgrade. It raises the level, improves bearing capacity and stops moisture rising from below.
3. Base. A graded granular layer that is stronger than the one beneath it. It gives a hard, even surface ready to receive the asphalt.
4. Prime coat. A liquid asphalt product sprayed onto the base to bind the loose particles and help the asphalt bond to it.
5. Asphalt base course. A mix with larger aggregate that provides the structural strength of the pavement.
6. Tack coat. A bonding spray applied between asphalt layers so they stick to each other and act as one.
7. Wearing course. A finer mix that gives the final texture and takes the direct friction of tyres.

Not every project needs all of these layers at the same thickness. A small yard for family cars is very different from a truck park. Skipping compaction, or cutting the base layer short to save money, is the most common reason we see behind asphalt that settles after a while.

Why compaction matters so much

Compaction drives out the air voids between particles. A layer that is not well compacted gets squeezed later under the weight of vehicles, and that is when dips and waves appear on the surface. A layer can look flat on the day it is spread and still hide this weakness, because the problem only shows under repeated loading.

This is why we run compaction tests on every layer before starting the next one. It is also why the order of work matters as much as the materials. A layer that is covered before it has been checked can no longer be corrected without removing everything above it. When you review a proposal, look for each layer named separately, with its thickness after compaction and the test that will confirm it.

Asphalt mix and fill materials

Asphalt quality starts at the plant and ends at the roller. An excellent mix laid with unsuitable equipment or at the wrong time will not give a good result, and the reverse is also true. Understanding the materials helps you judge what a contractor is proposing.

The asphalt mix

Hot mix asphalt is made of graded aggregate of different sizes and bitumen, the binder that holds it together. The bitumen content, the type of aggregate and its grading decide the strength of the mix and how well it resists heat.

• A mix with too much bitumen softens in summer and forms waves and ruts under traffic. You may also see shiny patches on the surface.
• A lean mix with too little binder loses its particles. The surface becomes rough, ravelled and worn.
• A well-designed mix balances the two, so it stays firm in the heat and holds together under turning wheels.

Fill materials

The subbase and base layers need clean materials, free from excess clay and organic matter. Correct particle grading allows strong, stable compaction, because the smaller particles fill the gaps between the larger ones. Materials with the wrong grading or with too much clay never reach a firm state, however long the roller works on them.

Cheap fill that does not meet the specification saves money at the start and then costs several times as much in repairs. The damage usually appears as settlement, cracking or soft patches that come back after each repair, because the cause sits below the asphalt where a surface patch cannot reach it.

Where the mix comes from

Hot mix is produced at an asphalt plant. The distance between the plant and the site affects the temperature of the mix when it arrives. In large cities such as Riyadh, Jeddah and Dammam, plants are usually available nearby. On remote sites, deliveries need tighter organisation so that the mix arrives in a condition suitable for laying.

It is fair to ask the contractor where the mix will come from, how its temperature will be kept during transport and whether the trucks will be covered on the road. A clear answer to these questions is a good sign that the team plans the work rather than reacting to it on the day.

Equipment and the role of temperature

The right equipment, used at the right moment, turns good materials into a good pavement. Each machine on an asphalt site has a specific job, and leaving one out usually shows in the finished surface.

The main equipment

• Motor grader for levelling the soil and the fill layers and for setting the falls.
• Rollers of different types, steel drum and pneumatic tyre, to compact each layer according to its nature.
• Asphalt paver to spread the mix at an even thickness with a level surface.
• Tipper trucks to carry the mix from the plant while it keeps its heat.
• Distributor truck to spread the prime coat and tack coat evenly.
• Small hand roller or plate compactor for corners and for edges close to walls and kerbs.

Matching equipment to the site

Equipment size is chosen according to the area. Large machines cannot get into narrow villa yards, so we use suitable sizes and give extra attention to hand compaction along the edges. Corners, the space around manholes and the strip beside a wall are where large rollers cannot reach, and they are also where poor compaction most often begins.

On roads and in subdivisions, large equipment is faster and more accurate in achieving a level surface over long runs. A contractor who brings machines that are too small for a large area may struggle to keep the surface even, while one who tries to force large machines into a tight yard may damage walls, kerbs or the finished layers.

Temperature decides the result

Temperature is a critical factor. A mix that cools before it is spread cannot be compacted properly, however many passes the roller makes. It stays open and weak, lets water in and wears early.

This is why we coordinate delivery times with the readiness of the site, so the mix arrives, is spread and is compacted while it is still at the right temperature. The base must be ready, the prime coat cured, the paver and rollers in position and the crew prepared before the first truck arrives. Trucks waiting on site while the mix cools, or a paver standing idle because the next load is late, are both signs of weak planning. Good coordination is invisible on the finished surface, but its absence is not.

Types of asphalt treatment and when to use them

Asphalt is not one single product. There are several asphalt treatments, and each suits a particular use. Knowing these types helps you understand what a contractor is proposing and why.

How the choice is made

The choice depends on the type of traffic, the nature of the site, the condition of any existing surface and what the owner expects in terms of appearance. A new villa yard usually needs hot mix with a smooth wearing course. A parking area where trucks stop may need modified bitumen or stronger layers. A long rural road with little traffic may be served well by surface dressing, if the owner accepts how it looks.

Be careful with cold mix

Some low-priced offers use cold mix over large areas, because it does not need a nearby plant or much equipment. This mix is meant for patching only. When it is used for a whole area, it breaks up and wears much faster than hot mix, and the owner ends up paying again for a proper surface.

If a quotation does not say clearly which type of mix will be used, ask. The name of the mix should appear in writing next to each layer, so there is no confusion later about what was agreed and what was delivered.

Drainage and surface falls

Water is the first enemy of asphalt. Water that ponds on the surface or seeps into the layers below weakens the fill and breaks down the mix over time. This is why drainage is part of the asphalt design itself and not an extra added afterwards.

Surface falls

Every asphalt surface needs a planned fall that directs water to a drainage point or off the site. On roads the fall usually runs from the centre towards both sides. In villa yards it runs away from the building towards the gate or towards a floor drain. In large parking areas the falls are spread in more than one direction according to the shape of the land, so that no part of the surface has to carry water a long way.

Drainage points

• Grated floor drains in the low spots.
• Linear channels beside the kerbs on internal roads.
• Connection to a stormwater network where one exists on the site.
• Planned soakaway areas in adjoining gardens where needed.

Asphalt level against the building

A common mistake is to let the final asphalt level rise until it comes close to the door threshold or to the level of the wall waterproofing. Water then sits close to the building instead of moving away from it, and can find its way into the walls or under the doors.

For this reason we set the levels from the start with a survey and review them with the owner before any asphalt is laid. Entrances, gates, garden beds and existing paving all have levels that the new surface must respect.

Drainage shows its value in the first rain

Good drainage does not show on handover day. It shows in the first rain, when the surface stays clean and the water goes where it should. A surface that looks perfect when dry can still hide a low spot that holds water for hours after a storm.

We recommend that you ask any contractor to explain the direction of the falls on the drawing or on site before work begins. If the answer is vague, or if the falls are left to be decided on the day of paving, treat that as a warning. Correcting a fall after the asphalt is laid means cutting and relaying, which leaves joints that are weaker than the original surface.

How climate affects asphalt across the Kingdom

Saudi Arabia is large and its climate varies widely. Asphalt laid in Riyadh faces very different conditions from asphalt in Jeddah or Abha. The choice of mix and the timing of the work take these differences into account.

The hot, dry central region

In Riyadh, Qassim and Al Kharj, the surface temperature rises sharply in summer. The risk here is softening of the asphalt and rutting under the wheels of parked cars. It is therefore better to use a bitumen suited to high temperatures, with good compaction and a well-designed thickness. During the hottest months it is also better to work in the early morning or in the evening.

The humid coast

In Jeddah, Dammam, Al Khobar and Jazan, humidity is higher and groundwater may be close to the surface on some sites. Moisture weakens the fill layers if drainage is poor. Here we give more attention to the quality of the subbase, to the falls and drainage points, and to stopping water from reaching the layers beneath the asphalt.

The cool southern highlands

In Abha, Khamis Mushait and Al Baha, temperatures drop in winter and rain is more frequent. Cold makes asphalt less flexible, so it cracks if the mix is not suitable. Laying in cold weather also calls for faster compaction before the mix loses its heat. Sloping roads in these areas need particular care with side drainage, because water runs quickly down the gradient and attacks the edges.

The northern and inland regions

In Tabuk, Hail and Al Jouf, the difference between day and night temperatures is marked. This repeated expansion and contraction tests the flexibility of the mix. Choosing the right mix and compacting it well reduce the cracking that results.

One method, adjusted to each site

The conclusion is that asphalt paving is not a single recipe for every city. The layers, the binder, the working hours and the drainage details all change with the region and with the conditions of each plot. A contractor that works in many regions knows how to adjust these details for each location, while keeping the same discipline of survey, compaction testing and supervision everywhere.

Planning parking areas and internal roads

Parking areas and internal roads are not just black open space. Good planning makes movement easy and safe and uses every part of the area. Poor planning causes congestion, minor collisions and rapid wear in particular spots.

Elements to think about before paving

• Entrances and exits. Their number and position relative to the public street. Separating the way in from the way out eases congestion in commercial complexes.
• Traffic direction. Whether aisles are one way or two way. One-way aisles allow narrower lanes and angled bays.
• Bay angle. Perpendicular bays fit more cars, while angled bays are easier to drive into and out of.
• Turning space. At the ends of aisles and at gates, especially where delivery vehicles or trucks enter the site.
• Pedestrian routes. From the bays to the entrances, so people do not have to walk between cars.
• Accessible bays. Close to the entrance, with a suitable ramp up to the pavement.
• Loading and unloading zones. For shops and warehouses, kept away from customer traffic.

A villa yard follows a different logic

In a villa, what matters is room for the family cars without one car having to move out so another can leave. The entrance should be wide enough to turn, and walking routes to the house doors and the majlis should stay clear. Many owners separate an asphalt area for cars from an area paved with interlock or stone for walking and seating. The choice between asphalt, interlock and concrete is worth comparing early, because each suits a different part of the yard.

Where wear is expected

Turning points at gates, stopping places in front of entrances and truck standing areas take the most pressure. Good planning identifies these spots early, so they can be given stronger layers or built in a more suitable material.

Shade structures

In the extreme heat, many owners choose to install car shades. Shade columns need footings that are built before the asphalt, or at least positions that are fixed in advance. Drilling into new asphalt to fix a column leaves a scar and a weak point around it.

Ask the contractor for a simple drawing showing the bays, aisles and falls before work starts. Changing the layout after paving means cutting and relaying, or accepting an arrangement that is never quite comfortable.

Edges, kerbs and manhole covers

Asphalt usually starts to fail at its edges rather than in the middle. An unsupported edge breaks up under wheels. The area around a manhole cover sinks or rises. The joint between asphalt and another material opens a path for water. These details deserve special attention.

Kerbs

Kerbs hold the asphalt from the side, stop the edge from breaking up and define the path of the water. They should sit on a firm concrete bed at the correct level, and they should be installed before the asphalt is laid, not after. A leaning or broken kerb leaves a gap through which water seeps into the layers beneath the asphalt.

Edges without kerbs

On some rural roads and at the boundaries of plots there are no kerbs. In that case the base layer should extend slightly wider than the asphalt, the edge should be well compacted, and it should be protected from erosion with compacted soil or gravel.

Manhole and inspection chamber covers

• The cover level is adjusted to match the finished asphalt surface.
• The area around the cover is compacted with a small hand roller, because large machines cannot reach it well.
• The cover frame is fixed in concrete so it does not move as cars pass over it.
• Covers are chosen to carry the expected load in that location, especially in parking areas and on roads.

Meeting other materials

Where asphalt meets interlock, concrete or a gate threshold, the joint should be clean and straight. The gap between the two materials is sealed with a suitable flexible product so water cannot enter. The change of level should be smooth, without a step for wheels to hit.

Cutting and joining to old asphalt

When new asphalt is joined to old, the old surface is cut in a straight line back to sound material. The cut face is sprayed with tack coat before the new mix is laid. Joining onto a broken edge leaves a weak line that cracks quickly.

Gates and ramps

At the main gate, asphalt often meets the track of a sliding gate or its threshold. The level must leave enough clearance for the gate to move without rubbing. On entrances that slope down from the street, the gradient should change gradually so the front of the car does not scrape the ground.

At handover, walk along the edges, around the manholes and at the gates. These places reveal the quality of the work more than the middle of the area does.

Preparing utilities under the asphalt before paving

One of the most frustrating situations is new asphalt that has to be cut soon after it is laid, to pass a pipe or a cable that someone forgot. The cut leaves a permanent scar and a weak line where water gets in. The solution is simple. Think about everything that will run under the asphalt before paving.

Checklist before paving

• Main and branch water lines to the house and garden.
• Sewer lines and inspection chambers.
• Stormwater network and floor drains.
• Power cables to outdoor lighting, gates and lighting columns.
• Cables for cameras, intercom and internet.
• Irrigation lines to planting beds and trees beside the driveways.
• Electric vehicle charging connections, if the owner is considering them for the future.
• Conduits for the automatic gate and its sensors.

Spare ducts

Even if you do not need anything now, placing empty ducts under the main driveways is a smart decision. The ducts are laid at a suitable depth, their ends are sealed and their positions are marked. When a need arises later, the cable or pipe is pulled through the duct without cutting the asphalt.

Compacting trenches

Trenches dug to pass services are among the most common causes of later settlement. They should be backfilled in layers, with each layer compacted well. A trench filled in one go looks level on paving day, then settles with use, and a sunken line appears along its route.

Protecting services from equipment

Heavy rollers can crack pipes that lie close to the surface. The depth of services is therefore confirmed before compaction, and shallow pipes are protected with a concrete surround or moved to a greater depth.

Coordinating the trades

On projects with more than one contractor, there must be a clear sequence. Plumbing, electrical and irrigation work comes first, then backfilling and compaction, then kerbs, then the pavement layers. Working with a single team responsible for all these stages reduces the chance of something being forgotten or of trades getting in each other's way.

Ask for a drawing that shows the routes of the services under the asphalt and keep it. Any technician working on the site later will need it, and it will save you from digging in the wrong place.

Road markings and safety features

Once paving is complete, it is time for road markings and safety features. This stage turns a black surface into an organised site where every driver knows where to stop and where to drive. It matters a great deal in commercial complexes, warehouses and the internal roads of subdivisions.

Types of marking paint

Safety features

• Bay lines and numbers, with arrows showing the direction of traffic.
• Marked pedestrian crossings at entrances.
• Speed humps on long aisles and near pedestrian areas.
• Reflective road studs along road edges.
• Wheel stops in bays facing walls or pavements.
• Clear signs for entry, exit and speed.
• Enough lighting to cover aisles and bays without dark patches.

The right time to paint

Paint applied to asphalt that has not cooled and settled enough may not bond well. The surface must also be clean, dry and free of dust. The site team therefore sets the marking date after paving according to the condition of the surface and the weather.

Speed humps done properly

A hump that is too high or too sharp annoys drivers and damages cars, while one that is too low does not do its job. It should have a gradual profile, be marked with clear paint and have a warning before it. It is better built from the same asphalt as part of the paving, or from well-fixed manufactured units. It must not block the flow of water towards the drainage points.

Re-marking over time

Lines fade with sun and friction, especially in the central region. Repainting along the same lines is easier and more economical than leaving them until they disappear and the layout has to be set out again.

In residential yards an owner may need only simple lines, or none at all. On sites used by the public, clear markings are part of people's safety and not decoration.

Quality checks you are entitled to ask for

Asphalt covers what lies beneath it quickly. Once it is laid, it is hard to know whether the layers were built as they should have been. This is why checks during the work are your real guarantee. You are entitled to ask for them and to see the results.

What you can see with your own eyes

• A surface of even colour, without shiny patches that point to excess bitumen.
• No loose particles or very rough areas.
• No roller marks or visible waves.
• Paving joints that are straight and tightly closed, not open.
• Firm edges at kerbs and manholes.
• Water flowing towards drainage points without standing.

Ask for the record

Ask for the test results to be recorded together with the location of each test on site. This record shows that every layer was checked before the next one was placed. It also becomes a reference if a problem appears later, helping to find its cause. The photos you receive during the work are part of this record, because they show each layer before the next one covers it.

Who carries out the tests

On large projects these tests are carried out by specialised independent laboratories. On small yards, field checks under the engineer's supervision are usually enough. What matters is that no layer moves on to the next without being checked. A contractor who is confident in the work will not object to you, or an engineer representing you, attending the tests.

A check after the first rain

Some defects only show with water. Watch the surface after the first rain, or after washing the yard with plenty of water. Photograph any spot where water stands and send it to the contractor so it can be dealt with under the warranty.

Rehabilitating existing asphalt

Not every old asphalt surface needs complete removal, and not every damaged surface can be fixed by laying a new layer on top. The right decision depends on the cause of the damage and how deep it goes. Diagnosis before treatment saves you a great deal.

Milling before a new layer

Placing a new layer directly on the old one raises the surface level. That can cause problems at gates, thresholds, manhole covers and kerbs. Milling removes the damaged old layer and keeps the level where it should be. It also reveals the condition of what lies beneath, so the team can tell whether deeper treatment is needed.

Cracks travel into the new layer

If a new layer is placed over cracked asphalt without treatment, the cracks reappear in the new layer after a while. Technicians know this effect well. Large cracks are therefore treated before paving, and in some cases a reinforcing grid is placed between the layers, depending on the condition.

Look for the cause first

• Does water collect at the damaged spot after rain?
• Is there a leak from a water or sewer line under the surface?
• Do heavier loads pass over the spot than it was designed for?
• Are there tree roots nearby?
• Was the damage above an old service trench?

Reusing milled asphalt

Material produced by milling can sometimes be reused in lower layers or in temporary tracks on site, with the engineer's approval. This reduces waste and saves cost on some projects.

If the cause is not treated, the repair will be repeated in the same place. This is why an inspection at Yam Integrated Construction starts by understanding the cause of the damage, then proposing the treatment that suits it and writing it clearly in the quotation.

Working on an occupied home or a trading site

Many asphalt projects take place on sites that cannot be closed. A villa where a family lives and needs to come and go every day. A commercial complex receiving its customers. A warehouse where trucks never stop. Working on these sites needs different planning from an empty plot.

Dividing the work into phases

The area is divided into sections, and each section is finished completely before moving to the next. An alternative route in and out is always kept open. In commercial complexes, the busiest parts can be done during quiet hours, such as early in the morning or after the shops close.

Safety

• Isolating the work area with clear barriers and warning signs.
• Keeping children away from equipment and hot mix.
• Guiding equipment movement with a banksman in tight spaces.
• Telling residents or tenants about working times in advance.
• Setting a safe place for the family cars outside the work area.

Protecting the surroundings

Hot mix and asphalt sprays leave stains that are hard to remove. Walls, gates, stone facades and adjoining interlock are therefore covered during spraying and paving. Manhole covers and drains are covered so that material does not get into them. Nearby plants and planting beds are protected from heat and spray.

Dust and smell

Milling and compaction raise dust, and spraying water reduces it. The smell of hot asphalt bothers some people for a short time. It is a good idea to close nearby windows during paving and to set the air conditioning to recirculate indoor air.

After each working day

The site is left clean and safe. Waste is removed and temporary edges are smoothed so that cars do not hit them. The owner is shown which areas can be used and which still need time before anyone drives on them. Mix should not be carried on car tyres into the house or onto the marble at the entrances.

Agree the plan before work starts

A team that respects the daily life of the people on site shows you how it will treat the rest of the work. Before the start, ask the contractor how the work will be organised on your site, how access in and out will be maintained and who you should call if a problem arises during the day. A clear answer, agreed in advance, avoids most of the friction that occupied sites can bring.

Asphalt in new subdivisions and projects under construction

In new subdivisions and compounds whose buildings are still under construction, conditions are different from a finished villa yard. Roads here carry concrete trucks, construction equipment and repeated digging to connect services. Planning must therefore consider every stage of the project, not only paving day.

Staged paving

A well-known approach on these projects is to build the lower layers and the asphalt base course first. The roads then become usable for construction traffic, and the fill is protected from rain and erosion. The smooth wearing course is postponed until heavy building work has eased. The roads are finally handed over with a clean surface that does not carry the marks of trucks and trenches.

What must be ready before paving

• Service connections to every plot, up to its boundary.
• Crossing ducts under the roads for future services.
• Entrance levels for each plot, so the pavement does not have to be broken later.
• Stormwater routes across the whole subdivision.
• Positions for lighting columns and signs.

Coordinating levels with the buildings

The road level sets the level of the entrances of the houses that will be built along it. If the road level changes after building, an owner finds the entrance higher or lower than the street. Final road levels are therefore fixed early and handed to owners and designers.

Protecting roads during construction

Routes are set for heavy truck traffic. Concrete trucks are not allowed to wash out on the asphalt. Contractors are asked to repair any damage they cause to the road. Roads are cleaned of mud and sand carried by trucks from excavation sites, because it blocks drains and hides defects.

Cutting for late connections

If an owner has to connect a service after the base course is laid, the cut should be made with a straight saw, and the trench backfilled in layers and compacted. The cut section is then relaid before the wearing course is placed over the whole road.

This approach suits developers and owners of residential and commercial compounds. It calls for a contractor who understands the whole construction process and not asphalt alone.

Maintenance after handover

Asphalt that is built correctly lasts a long time. Like any outdoor element, though, it needs simple attention that protects it from small damage before that damage grows.

In the first days

• Leave the surface until it has fully cooled before using it, as the site team advises.
• Avoid turning the steering wheel while the car is standing still on new asphalt.
• Do not place heavy stands or sharp equipment legs on the surface in the early period.

Regular care

• Clean the surface of sand and accumulated dust, because they grind against the surface and block the drainage paths.
• Watch where water collects after rain and report it early.
• Remove oil and fuel stains quickly, because over time they dissolve the bitumen.
• Inspect the edges at kerbs and drains, because they are the first places where the surface breaks up.

Treating cracks early

Small hairline cracks can be sealed with special products before water gets into them. Potholes and settlement need the damaged part to be cut out, the layers beneath treated and the area relaid. Delaying the repair lets the damage spread to the surrounding area, and a small patch becomes a larger job.

A protective seal coat

After some time, some owners choose a protective seal coat that restores the colour of the surface and closes its pores. This decision depends on the condition of the surface and how it is used, and we review it with you when the time comes. A seal coat suits a surface that is still structurally sound. It is not a cure for settlement or deep cracking, which need the causes underneath to be dealt with first.

Keep the drawings and records

Maintenance is easier when you know what lies under the surface. Keep the drawing of the services routes, the test records and the photos sent during the work. When a technician needs to dig, or when a defect appears, these documents show where the pipes run, how each layer was built and which parts of the work are covered by the written warranty. Simple habits like these keep a well-built surface in good condition for many years.

Choosing a contractor and reading the written quotation

Choosing an asphalt contractor is not a matter of comparing figures alone. Two similar prices can hide completely different work beneath the surface. A detailed written quotation is the clearest tool for revealing that difference.

Signs of a serious contractor

• Asks to inspect the site before giving any final price.
• Asks about the type of traffic and vehicles that will use the area.
• Explains the direction of the falls and the drainage points.

What a good written quotation contains

Warning signs

A price given over the phone without a site visit. A quotation that mentions asphalt with no reference to the layers beneath it. A contractor who suggests laying asphalt directly on bare earth. A refusal to put thicknesses in writing. All of these suggest that quality may be sacrificed in the parts you cannot see.

Questions to ask before signing

• Which engineer is responsible for my site, and how do I contact them?
• What happens if weak soil appears during excavation?
• How will the kerbs and walls be protected during paving?
• When can the surface be used after completion?

At Yam Integrated Construction, the written quotation follows a site inspection and sets out all of these items. You follow the work through photo updates, so you can see the layers before the asphalt covers them. We work the same way in Riyadh, Jeddah, Dammam, Abha, Tabuk and the other cities of the Kingdom.

How Yam Integrated Construction works

Our head office is in Riyadh, in the Al Suwaidi district, and we carry out asphalt paving in Riyadh, Jeddah, Makkah, Dammam, Taif, Abha, Tabuk, Buraidah and other cities across Saudi Arabia. Our way of working is the same on every site, whether it is a villa yard, a compound parking area or an internal road.

Our working method

• Site inspection. We survey the levels, assess the condition of the soil and confirm the type of traffic expected.
• Written quotation. It sets out the area, the layers, the thicknesses and the materials item by item.
• Engineering supervision. Every stage is supervised, with compaction tests before moving on to the next layer.
• Photo updates. Sent to you during the work, so you can follow progress from wherever you are.
• Written warranty. Documented in the contract, stating what it covers and its duration according to the type of work.

One responsible team

We work with a single team that is responsible from inspection to handover. The person who measures is the person who plans, and the people who build are the people who follow up. Your rights do not get lost between several parties, and there is always one point of contact who knows the full history of your site.

This matters especially in asphalt work, where so much depends on what happens before the final layer goes down. The same team that checks the soil also coordinates the services under the paving, sets the falls, confirms the kerbs and edges, and records the tests for each layer. Nothing is handed from one contractor to another with details lost along the way.

Before you request a quotation

If you want to understand what drives the cost of your project before asking for a quotation, it helps to think about the area, the type of traffic, the condition of the existing ground and the drainage the site needs, since these are the points we review during the inspection.

When you are ready, send us your location and the approximate area through our contact page, and we will arrange an inspection visit. After the visit you receive a clear written quotation, so you know exactly what will be built under the surface as well as on top of it.
