Asphalt Repair Raleigh
Asphalt Removal and Replacement
Over time, all pavement structures start to exhibit various types of failures. The asphalt will begin to crack, the cracking may become more widespread like a spider web. Potholes may form and worsen overtime, etc. Regular maintenance of your parking lot should include addressing these issues. Depending on the severity of the issue, the cause, etc., we can help create some options to address and repair the issue.
The most common repair we perform for distressed areas is asphalt removal and replacement. This involves removing the damages section of asphalt, and replacing it with new asphalt that is equal to or greater in depth than the existing. It is important to try and remove the entirety of the damaged area for replacement to prevent compromising the new repair with surrounding asphalt that is still compromised. another important factor is the depth of repair. Most light duty parking lots will have between 2″ and 4″ of asphalt existing. We like to go back with at least what was there, if not more to ensure the repair holds up. This will also depend on the circumstances that lead to the failure.
Patching is a cheaper alternative in areas where the asphalt has cracked, but the base is still stable, or in areas where potholes have occurred. This process begins by cleaning the repair area and applying a tack coat to help the new asphalt adhere to the existing surface. A layer of asphalt is then installed upon the existing surface; the depth will vary from 1”-2.5” depending on the severity of the existing damage. Patching is more affordable, however it will not last nearly as long as removal and replacement. Eventually cracking will reflect through the new patch, or spread beyond the patch.
With either removal and replacement or patching, the repair should reasonably encapsulate the distressed area. If the area of the patch is not large enough, there is a strong possibility that the asphalt will start to fail outside the patch, necessitating the future removal of both the patch and the newly distressed area.
When reviewing estimates, pay attention to how many square feet or square yards the contractor is intending to repair. Pay attention as well to the depth of the repairs. Some contractors may figure less asphalt thickness to win the job, but you will pay for that in the long run if it quickly fails. Always feel free to call us with any questions or clarifications you may need. At the end of the day, we want the customer to be happy with what they get.
