Paving Asphalt Driveway


Asphalt driveways are increasingly popular among homeowners because they are less expensive than pavers and perform during winter weather conditions. Find the best Asphalt Paving Mesa.

Step one in creating an asphalt driveway is to prepare its base, including installing subgrade material, geotextile fabric, and two lifts of runner crush stone.


Many homeowners with tarmacadam driveways may not recognize the need for a sub-base and, as a result, attempt to save money by forgoing one altogether. Unfortunately, this can be an ostly mistake, with paving eventually sinking or shifting over time as it sits atop an uneven sub-base layer. Luckily, it may still be possible to remove your current tarmacadam drive, check and level its sub-base, and then lay new pavers onto its surface layer if this exists already.

Sub-bases are necessary to prevent the pumping of fine-grained subgrade soils that could otherwise lead to slab edges and joints heave, providing a level surface for pavement as well as preventing differential settlement.

Sub-base construction typically uses a variety of materials, such as crushed stone, gravel ,and recycled asphalt. To ensure optimal performance of a sub-base ,it must be well compacted with sufficient resistance against degradation during construction and traffic loading ,as well as possess high hydraulic conductivity to dissipate stress evenly across its area of coverage.

Ideal sub-base thickness should mirror that of the final profile of paving  and be checked and compacted to within +/-10mm tolerance, the minimum acceptable tolerance. Furthermore, it must be free from open textured or surface voids – tightness is critical to providing proper load-bearing capabilities that prevent heaves or faulting issues.


Once the sub-grade has been prepared and geotextile fabric installed, it’s time to install asphalt binder. This layer serves as the basis of your driveway or parking lot; its composition resembles petroleum-derived asphalt tar, providing vital support against the eight vehicles & and trucks driving over it repeatedly while helping prevent pavement rutting from happening over time.

Your choice of asphalt binder is essential to the performance of any new pavement project. Utilize industry research, including published studies and laboratory testing, to select an optimal binder. When making this selection, take into account both environmental factors and traffic load considerations as well.

Asphalt binders typically include polymers to enhance their performance and durability, such as Styrene-Butadiene Rubber (SBR) or Ethylene-Vinyl Acetate (EVA). Polymers can make asphalt binder more elastic while increasing moisture damage resistance; additionally, they can increase its age resistance while decreasing thermal fatigue cracking susceptibility.

The global asphalt binder market is highly dynamic, with various factors influencing demand for its materials. Rapid infrastructural growth in emerging economies is driving increased asphalt binder use; warm mix asphalt technology is also becoming more widely adopted due to reduced energy usage and environmental impact.

Top layer

The surface course is the final layer of your asphalt driveway and the last point of contact between traffic loads and your pavement layers. It provides features like smoothness, noise control, rut resistance,and drainage while preventing water seepage into its underpinning layers of pavement.

The thickness of the surface course is an integral element when selecting an asphalt installation project. Paving contractors recommend 3 inches for residential driveways and 4 inches for heavy vehicle applications, although this can be adjusted according to your intended use and budget for any particular installation project.

Like concrete, asphalt requires an exceptionally well-constructed subbase rather than thick top layers to ensure its strength and weight resistance. Otherwise, its flexibility could diminish and eventually crack over time if overstretching occurs during installation or improper construction practices are used in its creation.

When pavement shows signs of wear and tear, there are two options for repair: overlay or remove and replace. An overlay involves rolling new blacktop over existing asphalt pavement; this method is less costly but does not last as long.

Under a removal and replacement approach, old asphalt must be stripped back down to its subgrade (runner-crush stone base) before rebuilding with a new base covered by geotextile fabric and compacted.

Transitional areas

Asphalt driveways are an economical and eco-friendly alternative to concrete, making an excellent residential option. Asphalt is less costly, has a longer lifespan, and blends in perfectly with sidewalks, garage floors, and other paved surfaces around your house – though paving asphalt requires special consideration in transitional areas to ensure it lines up perfectly with other paved elements and transfers weight efficiently – critical elements in its longevity and lifespan.

First, the old surface must be demolished and removed using heavy machinery such as bobcats, front loaders, and forklifts. Next, the sub-base is graded and compacted before being sloped for proper water drainage – an essential step as poor drainage often causes asphalt damage such as heaving or cracking.

Once the base is graded and compacted, the binder and surfacing stage begins. Asphalt pavement top layers consist of aggregate, oil, and various binder types mixed t which professional installers will then apply using proof roll installation with butt joints and transitions as necessary to blend into their current driveway or parking lot surfaces seamlessly.

Once finished, newly paved asphalt should be allowed to cure for three days before driving on it. To speed up drying times in hotter environments, this step should take place during cooler weather months.
