摘　　要：研究了水泥稳定砂砾基层的强度形成机理、收缩与抗裂特性,并对水泥稳定粒料基层的配比设计方法进行了分析探讨,从而确定水泥稳定砂砾基层配比,保证了水泥稳定砂砾基层强度的形成,以确保公路路面的施工质量。The strength formation mechanism of cement stabilized gravel stratum as well as＇its shrinkage and crack resistance characteristics is studied. The mix proportion design method of cement stabilized gravel stratum is also discussed in order to determine proper mix proportion of cement stabilized base to meet requirements on strength and ensure the construction quality of highway.
