摘　　要：通过掺加不同剂量的土壤固化剂和水泥稳定砂土的室内试验,结合工程实际,确定了高速公路工程中路床、底基层、下基层的配合比,并对各组配合比进行抗压回弹模量和干缩试验。研究结果表明,各组配合比抗压回弹模量能够满足规范及设计参数的要求,干缩系数较小。按此配合比铺筑的试验路段,工程质量良好。Through indoor test of mixing soil stabilizer and cement stabilized sandy soil in different dosages and combined with engineering practice, the proportions in roadbed, subbase and base of highway engineering are confirmed; then the tests for compression rebound modulus and drying shrinkage in the group of proportions are carried out. The study results show that the compression rebound modulus in the group of proportions can meet the specification and design parameters with small drying shrinkage coefficient. The test section of the highway paved in the proportions reaches ~ood en^ineerin~ aualitv.
