针对日趋严重的重载交通问题,文章以现行沥青路面设计规范为基础,对交通参数,结构组合设计和厚度计算等方面进行了研究,建立了重载交通轴载换算公式,推荐了适宜于重载交通的沥青路面基本结构,提出了以疲劳强度为设计标准,以极限强度为验算标准的沥青路面结构厚度设计方法。文章提出的方法,对于指导重载交通沥青路面设计具有一定的实用价值,但在今后的应用实践中有待进一步总结完善。
Aiming at the increasingly serious problem of heavy traffic, this paper studies the traffic parameters, the design of the structure combination and the thickness calculation based on the current asphalt pavement design code, and establishes the conversion formula of heavy load traffic axle load, The basic structure of asphalt pavement with traffic is put forward, and the thickness design method of asphalt pavement with fatigue strength as design standard and ultimate strength as checking standard is put forward. The method proposed in this paper has certain practical value for guiding the design of heavy-duty traffic asphalt pavement, but it needs to be further summarized and improved in future application and practice.
