Analysis and control of smoothness of cement stabilization gravel subbase;

In the light of the influence on the factors such as the strength and altitude in the road construction of the gravel subbase with cement stabilization,this article proposes the measures of controlling the subgrade quality,mixing quality,water content of the mixed materials,delay time of operation,maintenance conditions and loose paving coefficients,etc.

5 berths ,Jingtang Port,the detail technical measures and constructioin effect of cement stabilizing gravel-sand cushion course in the construction of storage yard are described in the paper.
