通过室内试验对3种不同粗集料含量水泥稳定碎石的强度、模量、收缩性能以及抗冲刷性能进行了测试。试验结构表明:在水泥用量、养生条件相同时,粗、细集料含量适中的水泥稳定碎石的抗压强度、抗压回弹模量略大于粗集料含量较少而细集料含量较多的水泥稳定碎石;粗集料含量较少而细集料含量较多时水泥稳定碎石的劈裂强度、抗折强度、抗折回弹模量最大,粗集料含量多而细集料含量少的水泥稳定碎石的各种强度、模量最小;粗集料含量较少而细集料含量较多的水泥稳定碎石平均温缩系数、平均干缩系数和冲刷量最大,粗、细集料含量适中的水泥稳定碎石次之,粗集料含量较多而细集料含量较少的水泥稳定碎石最小。
The strength, modulus, shrinkage and erosion resistance of three types of cement stabilized macadam with different coarse aggregate contents were tested by laboratory tests. The experimental results show that the compressive strength and compressive resilience modulus of cement-stabilized macadam with moderate content of coarse and fine aggregates are slightly larger than that of coarse aggregate and fine aggregate when the cement dosage and health condition are the same More cement stabilized macadam; when the content of coarse aggregate is small and the content of fine aggregate is large, the splitting strength, flexural strength, maximum modulus of rebound elasticity, coarse aggregate content and fine aggregate content of cement stabilized macadam The strength and modulus of the less cement stabilized macadam are the least. The average temperature shrinkage coefficient, the average shrinkage coefficient and the erosion amount of the cement stabilized macadam with less coarse aggregate and more fine aggregate are the largest, coarse and fine Aggregate content of cement stabilized gravel followed, coarse aggregate content of more fine aggregate content of less cement stabilized macadam.
