摘　　要：针对现状武金堤路重载、超载车辆较多的特点,在加强超载管理控制的基础上,新武金堤路道路路面结构设计中考虑结构冗余,采用钢筋混凝土面层,贫混凝土和水泥稳定碎石基层组合,同时采取措施提高土基的回弹模量,从道路结构的面层、基层、土基各方面进行有针对性的设计,延长重载、超载情况下路面结构的使用年限。Aiming at the characteristics of many heavy load and overload vehicles on Wujindi Road, on the basis of strengthening the overload management control, it is to consider the structural redundancy and to use the combination of steel reinforced concrete surface, lean concrete and cement stabilized crushed stone base in the pavement structure design of new Wujingdi Road. Also the measures are taken to improve the resilient modulus of subgrade. The article introduces the especial design of the surface, base and subgrade of road structure so as to prolong the service life of pavement structure under the condition of heavy and overload.
