摘　　要：通过对原路材料进行材料组成分析,并且通过对几种不同配合比的冷再生材料的无侧限抗压强度、劈裂强度、冲刷性能的初步研究,对二灰冷再生材料的性能做出了初步评价。二灰冷再生材料基本可以满足规范对沥青路面的半刚性基层的要求。Abstract Purpose of research ： that＇s to research road usage performance of cooling recycled lime - fly ash asphalt materials ; Methods of research ： Seeing also＂ Test Program for Stable Materials of Unorganic Binder for Highway Engineering＂ （JTJ057 -94）as well as ＂Test Program for Asphalt for Highway Engineering and Asphalt Mixture＂ （JtJ052 -2000） ,the paper analyzes composition of original road materials,and preliminarily evaluates behavior of cooling recycled llme - fly ash asphalt materials by way of tentative studdy of washout performance, cleavage strength and unconfined compression strength of cooling recycled materials with different proportionings;Results of research ： the unconfined compession strength and cleavage strength of cooling recycled materials add with prolongation of curing age, the wash - resistance of cooling recycled materials is not as good as one of standard lime - fly ash macadam. Conclusions of research ： the cooling recycled lime -fly ash asphalt materials could basically satisfy specification＇s needs for semi - rigid base of asphalt pavement.
