摘　　要：通过水泥稳定碎石的一系列试验,研究了复合型外加剂对水泥稳定碎石的无侧限抗压强度、间接抗拉强度、抗压回弹模量及收缩性能的影响规律。试验结果表明,复合型外加剂有效地改善了水泥稳定碎石的各项力学性能和物理指标,缩短了水泥稳定碎石基层的养生时间,达到了提前铺筑面层、开放交通的要求。In this paper, a series of experiments are carried out, the influnces of compound admixture on the unconfined compressive strength, indirect tensile strength, modulus of compression and contraction of cement-stabilized macadam are studied. The results indicate that compound admixture could improve the mechanical properties and physical indicators of cement-stabilized macadam effectively, shorten the conservation time of cement-stabilized macadam, pave the surface and open traffic in advance.

关 键 词：水泥稳定碎石 无侧限抗压强度 收缩 复合型外加剂
