High friction surface treatment (HFST) is a safety-first pavement treatment intended to restore and maintain pavement friction to reduce crashes. The cost of HFST is high compared to typical maintenance treatments; however, HFST is highly effective at reducing wet-weather and run-off road crashes. Improvement in the state of the practice can promot

Highway agencies seeking a more viable way to check the quality of asphalt construction than through sample cores are considering dielectric profiling systems (DPS) as a solution. DPS use a ground-penetrating radar (GPR) to collect dielectric values from the underlying surface that help measure air voids or nonuniformity of newly laid hot-mix aspha

State Departments of Transportation (DOTs) are continually assessing and choosing materials or technologies to meet their transportation needs. As part of this assessment, DOTs are turning to Environmental Product Declarations (EPDs) to quantify the environmental impacts associated with those products.
