Sealcoat wear indicated by bare asphalt patches
Detailed Description
The abrasive action of car tires and snow plows causes sealcoat to wear off. Here, light-colored patches indicate where the sealcoat has worn off and the underlying asphalt shows through. Applicators generally recommend reapplication every 3 to 5 years. Read more about coal-tar-based sealcoat and PAHs here.
