The Analysis and Evaluation of Buton Rock Asphalt Mixture Performance

Abstract

The modification mechanism of Buton rock asphalt is physical modification, without changing the original structure of the mixture, joined the Buton rock asphalt, rutting depth deformation of asphalt mixture decreases. It can improve the dynamic stability, and high temperature stability has improved significantly. Buton rock asphalt mixture anti water damage material performance improved slightly, bending stiffness modulus is lower than that of the common asphalt mixture. Comparative analysis of various performance tests, 25% of the dose of the Buton rock asphalt to improve the performance of asphalt mixture is the best.
