混凝土路面碎石化加铺技术研究

Research on Paving Technology of Concrete Pavement

对混凝土路面改造技术中常用的碎石化加铺技术进行研究,分别对破碎后的水泥混凝土板、水泥稳定碎石基层以及沥青面层的回弹模量和回弹弯沉进行试验检测。试验结果表明:在相同破碎时间下,相较于1.2 m和1.4 m的落锤高度,当落锤高度为1.3 m时,能够使破碎后水泥混凝土以及水泥稳定基层其承载力更佳。

In this paper,the common paving technology of concrete pavement is studied,and the resilience modulus and resilience deflection of broken cement concrete slab,cement stabilized gravel base and asphalt surface are tested respectively.The test results show that under the same breaking time,when the drop hammer height is 1.3 m,the bearing capacity of the crushed cement concrete and the cement stabilized base is better than that of 1.2 m and 1.4 m.
