煤矸石道路基层混合料试验与应用

Experiment and Application for the Gangue Road Base Course Mixture

本文研究了利用煤矸石代替砂石做道路基层混合料的施工工艺,对这种基层混合料的配合比,抗压强度,抗冻融性及水稳性等性质做了许多测试工作.并在实际工程中试推广使用.结果表明用煤矸石代替砂石做道路基层混合料在技术上是可行的.并具有明显的经济效益和社会效益,建议广为采用.

In this paper,the constructing technology of base course mixture made by gangue instead of sand,have been researched.Many experiments have been made,for mixture ratio,compression strength,freeze-thaw durability and water stability of the course mixture,and widely spread and applied in practical construction. The result demonstrates that,it is feasible in technology that road base coures mix- ture can be made by gangue instead of sand,and the benefits in economy and society are obvious.It can be advised to apply widely.
