分析了当前半刚性基层沥青路面中出现早期损坏的主要原因,并提出基于LSPM的新型路面结构组合,对新型“单粒径骨架连通空隙”结构的LSPM结构层分别从高温性能、水稳定性、透水性能、抗反射裂缝性能以及抗疲劳性能方面进行了分析比较,得出了LSPM是一种综合性能优良的沥青混合料。提出了基于LSPM的一系列新型路面结构组合,分别用于新建公路、旧路加铺改造等工程中。通过多年的工程研究与实践,给出了详细的施工控制流程和质量控制标准。
The main reason of early damage in the semi-rigid base asphalt pavement is analyzed and a new pavement structure combination based on LSPM is proposed. The LSPM structural layer of the new type of “single-grain skeleton communicating void” structure is improved from high temperature performance, water stability Properties, water permeability, anti-reflection crack performance and fatigue resistance were analyzed and compared. It was concluded that LSPM is a kind of asphalt mixture with good comprehensive properties. A series of new pavement structure combinations based on LSPM are proposed, which are respectively used in the construction of new roads and old roads. Through years of engineering research and practice, a detailed construction control process and quality control standards are given.
