浅析抗车辙路面沥青面层材料级配组成

沈阳-山海关高速公路路面在交通量大、重载超载车辆多、使用基质沥青的情况下,一些路段在通车5年后仍呈现出较好的抗车辙性能,结合“沈山路面后评价”课题研究成果,对其材料组成进行试验研究,并提出建议的级配范围和提高路面抗车辙性能的主要措施。

Superficial Analysis of Gradation Composition of Asphalt Surface Materials on Rut- Resisting Pavement

On Shen-Shan Freeway,some sections have still presented a better performance of rut-resistance after opening to traffic for 5 years in a big traffic volume,more vehicles of heavy load and overload along with the pavement applying the matrix asphalt.In the light of achievements studying the problem"After Evaluation of Shen-Shan Freeway's Pavement",the paper performs testing study of materials composition of the pavement,and puts forward the grading limitation and the major measures for enhancing rut-resistance performance.
