The Asphalt pavement is the most preferred process amongst the contractors in the construction industry due to its adhesive and waterproof properties.
However, asphalt pavement installation can be an extremely complex and difficult process that must be done under the expert’s guidance only so that these experts can help you seek all your asphalt paving solutions effectively and efficiently. As it is never too late to learn something new, in this article, we have listed a step-by-step complete and correct process guide that will help you know more about asphalt pavement installation and the ways you can implement the same for your commercial properties or homes.
- Demolition and removal
The first step is to remove the existing surface such as asphalt, concrete, or pavers with the help of heavy machinery. The heavy machinery and excavators can include small bobcats, forklifts, front loaders, and large dump trucks. This way you will be able to get rid of debris and achieve a clean and blank canvas for your new asphalt pavement.
- Grading and sloping
With the help of advanced tools and technology, a surface is prepared for an appropriate water drainage system. Water drainage plays an essential role in your asphalt pavement installation process as water can cause major damage such as cracks, potholes, and heaving. Generally, laser-guided transits and automatic motor graders are used to create a surface that allows water to run off appropriately.
- Preparing the sub base
Another most important part of your pavement installation process is your sub-base. The sub-base helps in creating a stable surface to support the new pavement. The sub-base also acts as a frost barrier to fight against the freezing and thawing of the pavement due to winter. If you fail to prepare a stable sub-base then it can be difficult for the pavement to provide durability for a long period of time.
- Proof roll and repair
In order to ensure your sub-base is stable and ready to support the new asphalt, a process called proof roll is used by the contractors. In this process, a quad-axle dump truckload with 72,000 pounds is driven over the surface to repair flexing gravel and soft spots that occurred during the process.
- Binder and surface course
Moving ahead a binder layer will then be laid to ensure the new asphalt pavement adheres permanently and increases the strength of the pavement. The Binder layer is composed of large aggregate mixed with oil to create a strong and durable surface for long periods of time.
- Installation of the new asphalt surface
After installing the supportive structures of a new asphalt pavement surface, you can now move ahead to install the top layer of fresh asphalt to create a smooth appearance. This new surface of asphalt is made up of a small aggregate, sand, and oil to create a jet-black asphalt surface for a smooth and clean ride.
- Transition
Asphalt pavement often tends to connect with existing driveways, roadways, and parking lots of your area. These connecting points are called butt joints where old and existing concrete meets the new pavement. The contractor will ensure to create smooth transitions between these butt joints so that the difference between the surface is not visible.
We hope with the above-mentioned information you now have a clear understanding of asphalt pavement installation and will be able to make mindful decisions accordingly.
