Abstract:

Material characterization provides basic and essential information for pavement design and the evaluation of hot mix asphalt (HMA). This study focused on the accurate characterization of an Alaskan HMA mixture using an asphalt mixture performance tester (AMPT) and an asphalt pavement analyzer (APA). The tests performed on the AMPT included dynamic modulus (|E*|), flow number (FN), and flow time (FT). The APA was used to measure the rutting resistance of HMA. A catalog of |E*| for typical Alaskan HMA mixtures is provided, and the prediction models of |E*| have been verified. The modified Witczak model (G* based) is recommended for estimating |E*| HMA when measured G* of binder is available, and the Witczak model (ŋ based) is recommended when default inputs of binder are used. The correlations between the results from the AMPT (i.e., |E*|, FN, FT) and the rutting depth obtained from the APA have been statistically analyzed.
