High-Temperature Stability of Asphalt Mixture with the Influence of Styrene Butadiene Styrene
چکیده انگلیسی

High temperature stability of asphalt mixture is used to evaluate the performance of asphalt concrete pavement. It is very important for engineers to improve pavement performance by analyzing factors that contribute to high temperature stability for asphalt mixtures. Based on the wheel tracking tests in laboratories, three types of asphalt mixtures with styrene butadiene styrene (SBS) modifier are used to analyze the high temperature performance of asphalt mixtures. It is shown that the optimum contents of SBS modifier would be 5%∼6% in continuous-graded mixtures; Rutting Depth (RD) would reduce and Dynamic Stability (DS) would obviously increase with the increase of SBS modifier; the DS of the coarser asphalt mixtures would be larger than that of the finer mixtures. The coarse aggregate could enhance friction of skeleton structure and mechanical interlocking force among mineral granule so that the shear strength and the high-temperature stability of the hot mixed asphalt mixtures would be significantly improved.
