长大纵坡路段抗车辙沥青路面的设计及应用

摘要

针对沥青路面特别是长大纵坡路段车辙的成因，分析抗车辙沥青路面设计对策，包括沥青路面结构层设计和沥青混合料设计。实际应用表明，通过加大沥青层厚度，优化沥青混合料性能，能确保沥青路面良好的抗车辙性能，促进路面使用性能提升。%This paper introduces the causes of asphalt pavement rutting,especially in long and steep sections,pavement design and analysis of anti rutting asphalt,mainly including the asphalt pavement structure layer design and asphalt mixture design.Application results show that the addition of Dali green layer thickness and optimization of asphalt mixture performance can ensure good performance of anti rutting of asphalt pavement,and improve pavement performance.
