交叉口高性能抗车辙沥青混合料路用性能研究

Study on the Pavement Performance of High Performance Anti-rutting Asphalt Mixture at Intersection

为了研究交叉口抗车辙沥青混合料的路用性能,通过复合高性能改性剂及纤维增强技术,开发高性能抗车辙沥青混合料,并对混合料的水稳定性、高温稳定性、低温性能进行验证。结果表明:高性能抗车辙沥青混合料的高温性能十分优异,沥青混合料的抗车辙性能明显改善,水稳定性和低温抗裂性均满足设计要求。

In order to analyze the pavement performance of high performance anti-rutting asphalt mixture at intersection,based on the composite high performance modifier and fiber reinforcement technology,the high performance anti-rutting asphalt mixture was developed. And the water stability,high temperature stability and low temperature performance were evaluated. The results show that,the high temperature performance of high performance anti-rutting asphalt mixture is excellent,the anti-rutting performance of asphalt mixture is obviously improved,and the water stability and anti-cracking at low temperature meet the design requirements.
