摘要
结合实际工程阐述了旧水泥路面的加铺沥青(白加黑)改造施工,分析了水泥路面的病害情况并进行了定量评定,提出加铺沥青层的设计方案:4cm细粒式沥青混凝土+6cm粗粒式沥青混凝土+2.5cm应力吸收层,设计验算满足规范要求,施工与运营效果良好,可为类似工程提供参考。
Combined with the engineering practice,the article sets forth the reconstruction of old cement pavement overlaying asphalt,analyzes the disease of cement pavement and quantitatively evaluates,and puts forward the design scheme of overlaying asphalt layer.This design scheme is 4 cm fine grained asphalt concrete +6 cm coarse grained asphalt concrete +2.5 cm stress absorbing layer.The design checking calculation satisfies the standard requirements.The construction and operation effects are good.The relative experience can be referred for the similar projects.
