Study on Structure of Low-cost Cement Concrete Pavement of Country Road in Mountain Area

In order to make full use of paving resources,save project cost and improve pavement design quality,this paper starts from the affecting factors,such as traffic characteristics,soil foundation strength and paving materials to propose three such pavement structure forms as rock rip-rap cement concrete,small plate stone cement concrete and low intensity cement concrete,which correspond to construction resources features of country road in mountain area.Then mechanical analysis,with finite element software,and then economic comparison,is carried out in relation to the recommended pavement structures so as to determine the pavement structure with lowest project cost finally.
