摘　　要：采用正交试验设计方法,对16种集料级配的水泥稳定碎石试件分别进行无侧限抗压强度、劈裂强度和干缩等物理力学试验,探求集料级配组成对水泥稳定碎石物理力学性能的影响规律,研究结果表明:集料级配组成对水泥稳定碎石物理力学性能有较大影响,集料级配组成不同,其物理力学性能各异,强度愈高,干缩变形愈大。Orthogonal trail design method is used and series of physics and mechanics trials were done for 16 kinds of aggregate gradation, such as unconfined compressive strength trial, splitting tensile strength trial and dry shrinkage trial, to search influence disciplinarian of aggregate gradation composing on performance of physics and mechanics of cement-stabilized macadam. Results show： Aggregate gradation composing has bigger effects on physics and mechanics performance of cement-stabilized macadam, and different aggregate gradation composing has different physics and mechanics performance, the higher is the strength of cement-stabilized macadam, the bigger is its dry shrinkage deformation.
