摘要：
The damage of asphalt mixture occurs in asphalt-aggregate interphase. The strength was directly associated with the overall performance of mixture. In this paper, Marshall test was applied to investigate the high-temperature stability. The high-temperature stability, water stability and low-temperature performance of five types of asphalt mixtures were tested through Marshall test, and the correlation between road performance dynamic stability, freeze-thaw split strength ratio, and low-temperature flexural tensile strength and average angular coefficient of coarse aggregate was studied. Moreover, the correlations of asphalt-aggregate interphase strength to the pavement performance index of asphalt mixture were also established. (C) 2018 Elsevier Ltd. All rights reserved.
