摘要
Abstract
In order to study the effect of graphene dosage(1％,3％,5％)on the rheological properties of asphalt and the road performance of asphalt mixture,the high-temperature,medium-temperature and low-temperature rheological properties of asphalt were evaluated by dynamic shear rheological test,linear amplitude sweep test and bending beam rheological test,and its road performance was verified by rutting test,low-temperature beam bending test,residual stability and splitting tensile strength test.The test results show that the appropriate amount of graphene can significantly improve the high-temperature stability and medium-temperature fatigue performance of asphalt,and slightly improve the low-temperature performance.At the same time,after the addition of graphene,the high-temperature rutting resistance and water damage resistance of asphalt mixture are significantly improved,and the low-temperature crack resistance is also slightly improved.The recommended graphene dosage is 3％.关键词
