为了改善和提高二灰稳定碎石的路用性能,对骨架密实型二灰稳定碎石组成设计方法进行了系统研究。采用逐级填充方法确定集料级配;以集料捣实密度为基础,通过理论计算结合试验确定二灰与集料的最佳比例,从而使混合料形成骨架密实结构。并通过路用性能试验对骨架密实型二灰稳定碎石混合料进行检验。试验结果表明骨架密实型二灰稳定碎石混合料的各项路用性能指标均优于规范级配的二灰稳定碎石混合料的性能指标。 In order to improve and improve the road performance of lime-flyash stabilized macadam, a systematic study was made on the design method of solid-structured lime-flyash stabilized macadam. Aggregate gradation was determined by step-by-step filling method. On the basis of aggregated tamping density, the optimal ratio of lye ash to aggregate was determined by theoretical calculation and combined test, so that the mixture could form skeleton compact structure. Through the road performance test, the skeleton solid lime-lime stabilized aggregate was tested. The test results show that the road performance indexes of the dense solid lime-lime stabilized aggregate are better than the performance indexes of the lime-lime stabilized aggregate with standard gradation.
