为了对比分析高速公路修复工程中不同修复方案的抗车辙效果,采用不同的沥青混合料类型组成不同路面结构组合方案,在沥青混合料高温稳定性室内试验评价的基础上,铺筑试验路并进行跟踪观测。将各种类型沥青混合料室内车辙试验结果、试验路不同路面结构组合方案使用3年后的车辙深度检测结果与该试验路交通量组成进行对比分析发现:交通量和轴载是沥青混凝土路面使用过程中车辙深度的关键影响因素,我国的技术规范根据不同类型沥青混合料抗车辙能力确定技术要求的同时,更应根据交通量及轴载组成制定路面结构抗车辙能力的技术标准。
In order to comparatively analyze the anti-rutting effect of different repair schemes in expressway rehabilitation project, different asphalt mixture types are used to compose different pavement structure schemes. Based on the evaluation of high temperature stability indoor test of asphalt mixture, the test roads are paved and carried out Follow the observation. The rutting test results of various types of asphalt mixture and the results of rutting depth test after 3 years of different pavement structure combinations on test road were compared with those of the test road. The results showed that traffic volume and axle load were used by asphalt concrete pavement Process rutting depth of key factors, China’s technical specifications according to different types of asphalt mixture rutting ability to determine the technical requirements, but also should be based on the traffic volume and axle load composition of the road structure rutting resistance of the technical standards.
