Professional Recommendations For A Successful Asphalt Pavement Installation

Posted on

Successful asphalt installation is a combination of preparing the site fully with a good base and evaluating the area for any existing conditions that can lead to surface failure. Professional paving contractors can complete both of these tasks as they install a new pavement surface. Here are some guidelines as you hire the installation of your new asphalt pavement.

Remove Existing Damage

Before you can install any new asphalt pavement, you need to clear the existing site of materials and debris that are already in place. Whether this is weeds, construction debris, or an old asphalt pavement that has degraded and failed, you will need to clear it from the area. If your installation site contains old weathered and cracked asphalt materials, plan to have them cleared from the site. 

However, keep in mind that if the old pavement is still on the site, you can ask your pavement contractor about removing the chunks from the site and recycling them into new materials. A large amount of destroyed asphalt is recycled into new aggregate and asphalt mixture every day by professional contractors, and your asphalt professional may be able to recycle it on-site and install it into your new surface. Taking this path will help you by removing the old pavement for you and keeping the environment protected against excessive waste going into the local landfills.

Grade and Prepare the Site

The next part of the installation process is getting the soil ready for a layer of asphalt, which only needs to be a couple of inches thick to provide optimal support. As long as the soil contains a good amount of sand and gravel to aid in drainage, your new pavement can go right over the smooth and level surface. If there are drainage issues on that site, which may have caused a previous pavement to fail, your paving contractor can evaluate for and correct these issues. If there are any low spots or areas where runoff naturally flows through the site, your contractor may need to install a French drain below the asphalt grade to protect against erosion.

It may be necessary to add in a layer of drainage materials before they can install your new asphalt. This can be completed with a layer of angular gravel or crushed rock that is compressed together to form a strong layer with adequate drainage capacity. The foundation of your asphalt is one of the most important details for installing long-lasting pavement. If the foundation structure erodes away from moisture flow or becomes saturated with moisture that has nowhere to go so it freezes in winter, the asphalt will become cracked and heaved upward.
