This paper presents results from a laboratory study to identify a performance-based acceptance test for hot asphalt mixtures when constructing airport pavements designed to accommodate high tire pressure traffic. Four performance tests, intended to screen for rutting susceptibility, were performed on twenty-six HMA mixtures using one neat binder. Eight of these mixtures were also prepared with a polymer-modified binder. Results from four candidate tests are presented: Asphalt Pavement Analyzer (APA), triaxial creep, triaxial repeated load, and dynamic modulus test. Preliminary criteria associated with these tests that can be used to screen or select airport HMA paving mixtures are proposed. The efficacy of the screening tests and associated criteria were evaluated by constructing and trafficking full-scale pavements using an accelerated pavement tester.
