沥青混合料的抗车辙性能研究

沥青路面具有良好的路用性能，在道路建设中得到了广泛应用，在已建成的高速公路中，95％以上都采用沥青路面。随着交通量的增长、轴载增加、超载严重、渠化交通、近年来持续高温天气等因素的综合影响，车辙己经成为沥青路面早期破坏中最严重的破坏形式，严重影响路面的性能。从沥青混合料的材料、级配两方面，研究抗车辙性能，提出提高沥青混合料高温稳定性的措施，从而改善沥青混合料的路用性能。

Performance Research on Rutting Resistance of Asphalt Mixture

Asphalt concrete pavement was used widely in our country because of its excellent performance.More than 95%of the express-way used the asphalt concrete pavement.Under the influence of increasing traffic volume and axial load,overloading,tube running and the continuous high temperature,rutting on the asphalt pavement had become the most serious factor,reducing the running quality of the pavement.Studying the performance of anti-rutting ability of asphalt mixture,this paper puts forward the methods of improving the high temperature stability and application performance of asphalt pavement from aspects of row material and design graduation.
