Pavement Magazine Column May 2016: RTS Has Standards

PCTC’s May 2016 column in Pavement Maintenance & Reconstruction Magazine relates the history of development of PCTC and ASTM standards for refined coal tar-based pavement sealant (RTS). The standards grew out of a need for consistency in performance characteristics. Read the entire column here. Links to ASTM and PCTC standards and specifications can be found at the Standards section of this web site, here.

Interestingly, Tom Ennis – an employee (retired?) of the City of Austin and the man behind the Coal Tar Free America blog – has posted a comment on the column. PCTC celebrates Mr. Ennis’ right to his own opinion, while wishing he was more careful about the factual bases of his opinions.
