Abstract:This report documents a cooperative effort to collect, process, and make available information about successful methods of varying seal coat asphalt application rates across treated roadways to optimize aggregate retention and avoid wheel path flushing. This topic is of critical importance to maximizing value obtained from TxDOT's multi-million dollar preventive maintenance program. The primary source of the information was highly experienced TxDOT personnel. Researchers used a field interview process to capture knowledge that had been gained through years of roadway practice. Construction specifications and a field guidebook entitled Guide for Transversely Varying Asphalt Rates were developed. Captured field experience and knowledge was prepared for placement into TxDOT's knowledge management system and seal coat inspector training course.
