摘　　要：对不掺和掺用外加剂或水泥的二灰稳定尾矿料的无侧限抗压强度进行测试 ,从中选出较优的配合比 ,再从较优配合比混合料的劈裂强度、抗压回弹模量、干缩性和工程经济性等角度进一步优选出二灰掺量、石灰与粉煤灰比例以及外加剂种类与掺量 ,进而将其用作连云港市旧路面 1km试验路段基层材料加以验证 ,以便推广应用。By the strength testing of WKL stabilized by lime fly ash, the optimizing mixing proportions are chosen. The splitting strength, elastic modulus, shrinkage and engineering economy of them are also tested, then the mixing proportions are further optimized. I.e.. the proper lime fly ash proportion, and the kinds and quantities of mixture. They are applied to pave the base of test road one kilometer in Lianyungang and are validated to apply widely.
