1、摘要目前，水泥稳定碎石是我国公路建设中主要的半刚性基层材料，它具有良好的板体性、较高的早期强度和抗裂性能，以及较强的抗变形能力，因此已被广泛应用于高等级公路、城市道路和机场道路。但是水泥稳定碎石的收缩性较大，施工时若控制不好容易产生裂缝，使基层的性能受到影响。本论文主要研究在半刚性基层材料水泥稳定碎石中掺入适量的钢渣以后，基层材料的强度、回弹模量、干缩变形等物理力学性质与钢渣掺入量、钢渣的粗细程度、养护条件等影响因素之间的关系及其变化规律。并在此基础上根据水泥稳定碎石强度形成机理、干燥收缩机理和数理统计、方差分析、回归分析的方法分析不同粒径的钢渣和不同的掺

2、量对水泥稳定碎石的力学性能和干燥收缩性能的影响，最后得出钢渣对水泥稳定碎石的强度、干燥收缩有显著的影响，并提出了相应的建议。相信本论文的结论和建议对今后进一步研究掺钢渣的水泥稳定碎石性能具有一定的理论价值和参考依据。关键词：水泥稳定碎石钢渣抗压强度和劈裂强度回弹模量干燥收缩ResearchOilCharacteristicsofSlagwiththeCementStabilizedMacadamABSTRACTAtpresent．cememstabilizedmacadamiSthemainsemi—rigiditybasematerialinhighwa
