AN INVESTIGATION OF THE EFFECTIVENESS OF ASPHALT DURABILITY TESTS-INITIAL PHASE
This is the initial report for a study of asphalt durability by the use of laboratory-manufactured briquettes controlling as many variables as possible, viz. asphalt source and grade, aggregate source and grading, mixing temperature, mixing duration, compaction, and void content. The report details the design, mixing, compaction, and field installation of the briquettes which were prepared at three void content ranges using three asphalts and two different aggregates and then weathered at four different climatic sites. Approximately 900 briquettes were placed in special weathering trays at sites located in coastal, desert, valley and mountain environments. Also included are test results obtained using various laboratory procedures on the three asphalts used in the study. Testing of the briquettes is being done after one, two, and four years of field weathering. Comparisons between the laboratory weathering test results and field test results are being made as test results become available. /FHWA/
