Primary Topic: Pavement Testing
Description: The Federal Highway Administration conducted studies to validate Superpave binder and mixture tests using its Accelerated Loading Facility (ALF). The ALF is a full-scale pavement testing machine that applies one-half of a single rear truck axle load. Several other tests that have been developed to predict the performances of asphalt mixtures, such as wheel-tracking devices, are also being evaluated. Twelve pavements were constructed at the Turner-Fairbank Highway Research Center in 1993. The rutting and fatigue cracking susceptibilities of the pavements are to be determined using the ALF. This report documents the mixture designs, construction procedures, and quality control and quality assurance tests for the asphalt pavement layers.
