The Optimization Design of Mixing Ratio of ARAC-13 Rubber Asphalt Mixture based on Low Temperature Crack Resistance
IOP Conference Series: Earth and Environmental Science（2019）
Abstract
The representative ARAC-13 mineral grading range was calculated by power curve grading, combining with the climatic characteristics of Gannan high-altitude and damp areas. The gradation of five kinds of ARAC-13 rubber asphalt mixture was designed based on representative grading. Different grade rubber asphalt mixtures were studied by the freeze-thaw splitting test and low temperature bending test to optimize the mix design of ARAC-13 mixture.
