While there are several popular ways to help prolong the life of pavements, not all methods are equal in effectiveness, cost and environmental impact. One method, Coal Tar Sealant has quickly become of significant concern. Increasing studies have shown coal tar coatings to be prone to shrinkage, cracking and accelerated pavement degradation. Plus, USGS data confirmed that coal tar releases up to 1000 times greater toxins into the watershed than those released by asphalt pavement or asphalt based coatings. Read more here.
