Title: DIRECT TENSION AND SIMPLE STIFFNESS TESTS--TOOLS FOR THE FATIGUE DESIGN OF ASPHALT CONCRETE LAYERS
Accession Number: 00637689
Record Type: Component
Availability: Find a library where document is available Abstract: A design strategy with fatigue as the major concern and with a check on rutting was developed using creep and direct tension tests as simple tools. This design is appropriate for the heavy-duty asphalt concrete pavements subject to the environmental and traffic conditions that exist in the state of California. Two types of asphalt cements (AR 4000 and AR 8000) with the California standard 0.5-in. maximum size, medium grade, granite aggregate were used. Hveem stabilometer tests were used to derive the design asphalt contents. Uniaxial unconfined creep tests were conducted to determine the stiffness of the mix. The environments in the state of California were divided into five groups. Full-scale fatigue and direct tension tests were conducted for three temperatures. From these test results equations were developed to predict the fatigue life through the direct tensile stress and simple stiffness. Thus the fatigue testing program, which is time consuming and costly and requires special equipment, was eliminated. Finally several pavement case studies were designed, and the best of these were selected for each of the environmental groups.
