摘要
Abstract
Silicone rubber modified asphalt was prepared by using silicone rubber(SR)and 90#.The short-term and long-term aging tests of silicone rubber modified asphalt were simulated by rotating film oven test and pres-sure aging test.The rheological properties of silicone rubber modified asphalt before and after aging were test-ed by Brinell rotary viscosity test and dynamic shear rheological test.The results show that silicone rubber can significantly improve the aging resistance,fatigue life and high temperature stability of asphalt,but excessive addition(14%and 16%)will have a negative impact on the performance of srma.The optimum content of sili-cone rubber is 12%～14%.关键词
