Laboratory Tests for Predicting the Performance of Asphalt Concrete

Status:  Complete
Report Date:  12/31/2011

Summary:

Researchers conducted a literature review on asphalt performance tests to identify suitable candidates for inclusion in asphalt mixture specifications. Promising tests include the indirect tensile strength test, disk-shaped compact tension and semi-circular bend tests, the Texas overlay tester and the four-point bending beam fatigue test. Including a laboratory performance test in asphalt mixture specifications would improve the longevity of asphalt pavements and reduce the risk of early cracking, rutting and other deterioration.
