透水式水泥稳定碎石基层在市政工程中的应用

Application of Pervious Cement Stabilized Macadam Base in Municipal Engineering

经过试验路段的实践和常规试验检测方法的检测,证明在道路基层中引入水泥稳定开级配碎石透水层,施工机械设备投入不多,可降低工程造价,各项指标满足基层强度及透水性要求,可有效地补充地下水源,值得在市政道路工程基层及其他有排水要求的基层中推广应用。

Through the practice of test road and the detection of common test methods,it is proved that introducing open graded cement stabilized macadam pervious layer into road base,machines and equipments used in construction are less,various indexes can meet the demand of the strength and water permeability on base and the ground water can be supplied effectively.The practice deserves application and popularization in the base of municipal road engineering and the other base with drainages demand.
