Process For Asphalt Installation
What to expect when installing an Asphalt driveway, Car park or Road.
Whether you’re looking at installing a new residential asphalt driveway, a commercial carpark or looking to upgrade an existing road there are a few things to keep in mind when it comes to the installation process.
At High Quality Asphalt we equip our clients with the knowledge on the process and how to best equip yourself with the upcoming investment of any asphalt product.
Step 1: Demolition and Removal
The key to the very best outcome is always in the prep work, the first step in the asphalt installation process is to remove any existing surface.
Demolition and removal is completed using specialised heavy machinery, at High Quality Asphalt we are equipped with all of the machines needed to ensure optimal results. We then remove any debris and when suitable, recycle unwanted product.
Step 2: Grading and Sloping
Once the surface is prepped High Quality Asphalt uses state of the art technology and laser guided transits to ensure water runoff. This is an integral part of the preparation stage as proper water drainage ensures the longevity of your new Asphalt surface.
Step 3: Preparing the Sub Base
The most important part of your new asphalt surface is actually the sub base.
The sub base provides a stable surface to support new pavement.
The sub base is a frost barrier to help reduce winter damage due to freezing and thawing.
During the installation, base thickness, base stability, and compaction are essential steps. If the sub base is not appropriately compacted, the asphalt surface on top will not provide years of durability.
Step 4: Binder and Surface Course
Once the sub base is laid and any soft areas are identified and repaired, it is time to add the binder.
The binder layer is large aggregate mixed with oil, making it very strong and durable.
The binder layer provides the strength of any new asphalt surface.
Step 5: Installation of the New Asphalt Surface
Once the supportive structures of a new asphalt surface are installed, the top layer of fresh asphalt is added to provide a clean, smooth finish.
Surface asphalt is made up of small aggregate, sand, and oil.
This combination of materials creates jet-black asphalt that, when installed appropriately, provides a smooth ride and a shiny, attractive finished surface.
Step 6: Butt Joints and Transitions
It is very rare to install an asphalt surface that does not connect to existing driveways, roadways or parking lots. As such, asphalt-paving contractors must find a way to smooth the transition from old surface to new.
Butt joints are areas where old asphalt or concrete meets new asphalt pavement.
These transitional areas require special attention to ensure that the grading and water run-off is appropriate.
Final Step: The Last Roll
Once the asphalt and butt joints have been laid, the entire surface is smoothed and compacted.
Using a roller truck, the new asphalt pavement surface is compacted and smoothed.
This step ensures that no small bumps of aggregate or stone are left poking through the smooth new surface.
