水泥稳定砂岩碎石路面基层的性能研究

Performance Study of Cement-Stabilized Sandstone Gravel Pavement Base

水泥稳定碎石的基层材料一般会选择石灰石、砾石、花岗岩等,这些岩石的强度和压碎值较大,能很好地满足公路路面基层的需求。但是,很多地区在进行高速公路工程建设时,沿线优质岩石缺乏,以砂岩为主,如果能将这些砂岩有效地应用在半刚性路面基层中,实现就地取材,不仅能降低材料运输成本,还能对沿线的自然生态环境进行保护,有十分积极的现实意义。论文针对水泥稳定砂岩碎石路面基层的性能进行了研究和探讨,希望能为相关路面工程的施工建设提供参考。

The base material of cement stabilized macadam generally choose limestone,gravel,granite and so on.The strength and crushing value of these rocks are high,which can meet the needs of highway pavement base.However,in many areas of highway construction,there is a lack of high quality rocks along the route,mainly sandstone.If these sandstones can be effectively applied to semi-rigid pavement base and local materials can not only reduce the cost of material transportation,but also protect the natural ecological environment along the road,which has a very positive practical significance.This paper studies and discusses the performance of cement stabilized sandstone gravel pavement base,hoping to provide reference for the construction of related projects.
