水泥稳定建筑垃圾的路用性能研究
|
摘要
经过一系列的试验,对水泥稳定建筑垃圾的无侧限抗压强度、劈裂强度、抗压回弹模量、抗冻性、水稳定性等路用性能进行了研究,并分析了水泥稳定建筑垃圾的最大干密度与最佳含水量间的关系,以及水泥含量对水泥稳定建筑垃圾各项路用性能的影响。结果表明:水泥稳定建筑垃圾的强度和刚度较高、抗冻性与水稳定性较好,各项路用指标均满足规范对轻交通二级以下公路基层及底基层的材料要求。
Through a series of experiments, the road performance of cement stabilized construction waste, such as unconfined compressive strength, splitting strength, compressive resilience modulus, frost resistance and water stability, was studied. The relationship between the maximum dry density and the optimum moisture content of cement stabilized construction waste, and the influence of cement content on the road performance of cement stabilized construction waste were analyzed.The results show that the strength and stiffness of cement stabilized construction waste are higher, the frost resistance and water stability are better, and all road indicators meet the material requirements of the specification for the highway base and subbase under light traffic below Grade II.
