April 24, 2009 - Austin, TX
The TxDOT Regional Workshop on Transversely Varying Asphalt Rates (TVAR) was held in Austin on April 30. When applying seal coats, the asphalt rate can be varied across the width of the roadway in order to better address the needs of the existing pavement surface. The practice of TVAR can improve the performance of seal coats on pavements with flushed surfaces by adjusting the asphalt application rates to account for the difference between the wheel paths and the rest of the pavement. This workshop provided participants with detailed information regarding the use of TVAR, and concluded with a demonstration of the sand patch test – a valuable tool for the determination of proper asphalt rates..
