Thin Coat Repair Case Study
North Carolina Department of Transportation Repairs Shallow ¼” Depression With Perma-Patch
Published: September 5, 2022
In July 2010, a pothole developed in a travel lane of a busy rural road. Due to the pothole, water penetrated the road’s surface and created a ¼” depression, increasing the danger for drivers on the road.
Since the North Carolina Department of Transportation D5 Streets Maintenance team previously used Perma-Patch on other pavement repairs, they quickly entrusted Perma-Patch to repair this depression as well.
Perma-Patch Regular Mix was used to repair the shallow ¼” depression by using a thin coat application. A vibratory compactor plate was then used on the thin coat application to create a watertight bond.
After two years, the repair was reported to still be effective.
