Superpave has become the hot-mix asphalt mixture design method of choice of most state highway agencies across the United States. Early performance tests showed very rapid rutting failures. In order to determine the causes of the rapid rutting failures, a team of academicians, asphalt industry experts, and state highway officials was established to study the early failures and to provide recommendations to revise Superpave design procedures. The Superpave Mixture Design Guide was prepared by this team to establish a good guide on the design of Superpave mixtures and to be a useful companion to the National Asphalt Pavement Association’s “Superpave Construction Guidelines”.
In this course, the student will review the U.S. Department of Transportation, Federal Highway Administration’s publication “Superpave Mixture Design Guide” (Feb. 2001).
The student must take a multiple-choice quiz consisting of fifteen (15) questions at the end of the course to obtain PDH credits.
