摘要
结合湖北省某三级路改造的工程实践,采用最新《公路水泥混凝土路面设计规范》所述方法,对旧水泥混凝土路面进行了路面损坏状况调查评定、接缝传荷能力和板底脱空状况调查评定和路面结构参数调查等。并针对不同路况,提出了相应的沥青层加铺改造方案。
Paving asphalt overlay is one of the most commonly used measures in reinforcement and reconstruction of old cement concrete pavement. It can improve the pavement performance efficaciously and economically. The recon- struction engineering practice of tertiary highway in Hubei Province is combined with in this paper. According to the latest ＂Specifications for Design of Highway Cement Concrete Pavement＂, we successively investigated the pave- ment distress condition, joints＇ load transfer ability, slab suspending condition and pavement structure parameters, and then analyzed and evaluated them. Finally aiming at the different pavement conditions, various asphalt overlay schemes is put forward.
