- Abstract:
- In order to improve the road performance of asphalt mixture and take into account the good weather resistance, high-speed shearing machine was used to prepare different amounts of SEBS modified asphalt. Various performance indicators were measured and their influence on the road performance of the asphalt mixture was studied. The high temperature, low temperature, water stability and fatigue resistance of SEBS modified asphalt mixture were evaluated by high temperature stability test, low temperature crack resistance test, freeze-thaw splitting and water-immersed Marshall test and four-point bending fatigue test. The test shows that the dynamic stability of asphalt mixture increases with the increase of SEBS content, and the increase is smaller when the dosage exceeds 4% SEBS has a significant effect on improving the low-temperature performance of asphalt mixtures and water stability after freeze-thaw cycles The fatigue life of the post-mixing material is reduced, but the initial stiffness modulus is significantly higher than that of the matrix asphalt. After the secondary fatigue loading self-healing, the late modulus and fatigue life of the modified asphalt mixture are significantly better than the matrix asphalt, and gradually increase with the increase of the dosage, showing excellent self-healing properties
