摘　　要：结合泡沫沥青冷再生混合料的室内试验,探讨泡沫沥青再生二灰碎石混合料的设计及其优化方法。结果表明:采用马歇尔方法设计的泡沫沥青冷再生二灰碎石混合料,15℃干劈裂强度为0.65 MPa,满足路面基层强度要求;沥青用量对湿劈裂强度影响最为显著,干湿劈裂强度比的影响最小。基于灰色关联度方法,优化了泡沫沥青再生二灰碎石混合料设计方法,确定了最佳油石比。Through laboratory tests of foamed asphalt cold recycled mixture,this paper studied the design method of foamed asphalt recycled lime-fly-ash macadam mixture and its optimization method. The results showed that： the splitting strength of foamed asphalt cold recycled lime-fly-ash macadam mixture designed by Marshall method at 15℃ was 0.65 MPa,which meets the strength requirement of pavement base; asphalt content has the most significant effect on wet splitting strength,and the ratio of dry and wet splitting strength has the minimum effect. Based on the method of gray correlation degree,optimized the design method of foamed asphalt recycled lime-fly-ash macadam mixture was optimized,the optimum bitumen aggregate ratio was got.
