摘　　要：系统研究了不同再生粗集料掺量情况下水泥稳定碎石混合料的抗压强度、劈裂强度和水稳定性等路用性能,并与全新混合料进行了对比。试验结果表明,随着再生粗集料掺量的增大,水泥稳定碎石混合料的抗压强度、劈裂强度、水稳定性会有所降低。适当配合比的掺再生集料水泥稳定碎石的路用性能满足公路基层材料的要求。The highway performance of cement stabilized macadam mixture with different amounts of recycled coarse aggregate is studied systematically,including compressive strength,splitting strength and water stability in this paper.And compared with the technical properties of new aggregate mixture.The test results indicate that the compressive strength,splitting strength and water stability of cement stabilized gravel stone would decrease with the recycled aggregate content increased.The highway performance of cement stabilized gravel mixed with recycled aggregates in an appropriate ratio meets the requirements of highway base materials.
