Frictional Resistance Of Aggregates For Hot-Mix Asphalt Pavements, Joan Patricia O'Brien, John E. Haddock
Frictional Resistance Of Aggregates For Hot-Mix Asphalt Pavements, Joan Patricia O'Brien, John E. Haddock
JTRP Technical Reports
In 1997 the Indiana Department of Transportation adopted the Superpave mixture design method and attendant specifications for hot-mix asphalt pavements. Prior to Superpave, the Indiana Department of Transportation aggregate frictional requirements were based on average daily traffic volumes and were divided into low, medium, and high volume categories. With the implementation of Superpave in Indiana, aggregate frictional requirements were reassigned to categories based on equivalent single axle load values. The purpose of the research is to determine whether average daily traffic or equivalent single axle load has a greater effect on the frictional resistance of a hot-mix asphalt pavement, to …
