加铺沥青层的旧混凝土路面结构参数调查与评定

以旧混凝土路面上加铺沥青层这个工程实例为依托,对旧混凝土路面接缝传荷能力,脱空板现象,旧水泥混凝土板的厚度,旧水泥混凝土板的强度,弯沉及弯沉差进行了调查评定,进而得出旧水泥混凝土路面基层顶面当量回弹模量测试方法。

Investigation and Evaluation of Structures and Parameters of Used Concrete Pavement Additionally Paved by An Asphalt Coat

Based on the project example of additionally - paving the asphalt coat on used concrete pavement, the paper investigates and evaluates the joints load transfer capacity, phenomenon of slab hanging in the air, thickness and strength of used cement concrete slab, deflection and difference in deflection, and has achieved the methods for testing equivalent modulus of resilience on the top of used concrete pavement base.
