PCTC Fights for Refined Tar-Based Sealer

This article discusses recent research sponsored by the Pavement Coatings Technology Council (PCTC). Their research contradicts data published by the U.S. Geological Survey (USGS) that linked polycyclic aromatic hydrocarbons (PAHs) in sediments to refined tar-based sealers. Instead, PCTC research suggests that refined tar-based sealers cannot be identified as the source of PAHs using the USGS analysis method. In another study, a before-and-after analysis shows that the amount of PAHs has remained unchanged since a 2006 ban on the use of refined-tar based sealers in Austin, Texas. In addition to continuing to study refined tar-based sealer in the environment, the PCTC is leading an effort to challenge bans on the use of refined tar-based sealers.
