摘要
为研究高掺量橡胶粉对SMA混合料的影响,选择胶粉掺量和纤维作为影响因素,制备不同掺量的胶粉和纤维,结合试验段评价情况,研究高掺量橡胶沥青混合料路用性能。研究表明:橡胶粉掺量为25%时混合料粘度体系最大,不掺纤维对混合料性能更优异,尤其高温性能更突出。
In order to study the effect of high-volume rubber powder on SMA mixture,this paper selects the rubber powder content and fiber as the influencing factors,prepares different rubber powder and fiber,and combines the evaluation of the test section to study the high-volume rubber asphalt mixture performance.The research shows that the viscosity system of the mixture increases when the rubber powder is 25%,and the performance of the mixture is better without the fiber blending,especially the high temperature performance is more prominent.
