摘要
根据旧路调查和FWD弯沉测试结果,确定再生深度,形成了泡沫沥青稳定碎石基层和泡沫沥青混合料面层两种冷再生方案,确定了稳定剂最佳剂量的选择方法,初步形成冷再生混合料的配合比设计方法。从后期观测情况来看,路面使用状况良好。
Based upon investigation results of older pavement and FWD deflection test results the recycling depth is determined as well as two cold recycling schemes of foam asphalt stabilized macadam base and surface layer of foam asphalt aggregate mixture. The selection method of optimum amount of stabilizer is determined so that the design method of mix proportion of cold recycling mixture is presented. Post construction observation show the service situation of pavement is good.
