高等级公路路面结构内部排水系统的研究与探讨

Study and Research in Drain away Inner Water on High Grade Highway Surface

通过对公路路面结构内部排水系统的研究和试验,证实沥青稳定碎石排水基层和水泥稳定碎石排水基层的配合比其抗压强度均能满足规范要求。这种路面排水结构基本上可消除唧浆现象,所用排水基层混合料与一般的同种混合料在施工上没有差别,容易控制。

Through the test and research in drain away inner water on highway surface ,it proof that the basis strength in drain away water of cement and pitch stabilized graded macadam are satisfied the needs of regulations.Otherwise ,the drain away water method could almost clear up the appearance of spurt liquid.This is mix-material is not difference with the other mix-material.It is easy to control.
