半刚性路面在辽阳市新运大街改建设计中的应用研究
|
摘要
本文在辽阳市新运大街改建设计中，结合当地水文地质、气候与材料资源条件，成功应用了半刚性路面结构，分析了半刚性路面结构强度形成机理，分析了诸如裂缝、冻胀和翻浆等病害的形成与防治措施。从材料分析的角度，提出了半刚性基层强度、稳定性与耐久性的技术要求。从结构设计的角度给出了半刚性结构在辽阳地区的适用结构型式，并与以往工程实例的对比，分析了半刚性路面的技术经济性。
In this paper, considering the local hydrology and geology climate and material resources in Liao Yang Avenue reconstruct engineering, semi-rigid pavement structure has been applied to analyse forming reason and preventing measures of the damages such as cracks thaw and frost boiling.
According to material performance, some technical indexs about stability durability and intensity of semi-rigid base have been put forward. And then with the consideration of structure design feasible structure form of semi-rigid pavement in Liao Yang Avenue, has also been supposed, and by comparing the engineering with former ones advantages and disadvantages about semi-rigid pavement have been discussed in technical and economic aspects.
