Abstract:In the design of Hot Mix Asphalt (HMA) there are tests performed on the aggregates such as resistance to abrasion, specific gravity and sieve/gradation analysis to ensure the aggregates are of sound quality prior to use in HMA. There are also tests performed on liquid binder such as temperature grading which ensure that the correct binder is being used and that its temperature performance is sufficient to withstand environmental impacts. Until recently there have been no performance tests that in a laboratory that indicate what sort of long-term resistance to deformation-type failures a HMA-pavement mix will provide. Researchers, users and producers of HMA have long sought a performance test that could be performed in the laboratory that would give an accurate indication of field performance. The asphalt pavement analyzer is a multifunctional testing device intended to provide a suite of tests that give an indication of field performance. This report describes CAP Lab's acquisition, set up and initial testing experience with the Asphalt Pavement Analyzer.
