摘要
基于路面使用性能的方法既考虑材料特点的影响,又不会受交通量和轴载的限制,是研究冷再生路面结构设计的有效的途径。介绍课题组经过多年研究的基于使用性能的沥青路面结构设计方法的设计思路和过程,然后通过分析典型路段多年技术状况的变化情况,反算得出基于性能的冷再生混合料相当于热拌沥青混合料的等效结构厚度系数。最后结合冷再生混合料的材料和结构参数特点给出基于使用性能的冷再生路面的结构设计方法的思路和流程。
An effective approach to studying cold recycling pavement structure design is to analyze the pavement performance, which considers the effects of material characteristics without limitation of traffic volume and axle load. This paper first introduced their previous research on the based on performance asphalt pavement structure design method, and then through the analysis of the longterm changes of technical conditions of typical sections, this paper proposed the back calculation method for the cold recycled mixture equivalent thickness coefficient to hot mix avsphalt mixture structure. Finally, with the consideration of the characteristics of cold recycling mixture materials and structures, this paper presented the idea and process of the based on performance cold recycling pavement structure design method.
