水泥混凝土路面板块加固罩面综合处治应用技术研究

Research on Integrated Treatment Applied Technology of Cement Concrete Pavement Plate Overlaying

水泥混凝土路面经过一定年限的运行,面层和基层在重载、超载等因素的影响下受到破坏,加之年久失修,各种病害日益加剧,故改造加固、实施必要的罩面已势在必行;对旧水泥混凝土路面采取补强加固方法,或采取破碎后改变结构性能使旧水泥混凝土保持一定的稳定强度,并在其上加铺沥青混凝土实施罩面,使得原面层具有平整度好、摩阻系数高、行车舒适等优点,也是今后国内水泥混凝土路面改造的趋势。结合施工实践,对水泥混凝土路面综合处治应用进行研究。

The cement concrete pavements service for a certain number of years, the surface layer and the base-course are damaged by the impact of factors such as heavy-duty and overloading, all kinds of diseases are growing, the reconstruction and strengthening, the implementation of the necessary overlay must be carried out. To take the old concrete pavement strengthening methods, or change the structure performance after breaking the old pavement will enable the old concrete to maintain the stability with a certain intensity, and the asphalt concrete overlay is paved to make the original surface with a roughness good, high friction coefficient, driving comfort, etc. , but it is also the future trend of the domestic cement concrete pavement reconstruction. In this paper, the research on construction practice of integrated treatment of cement concrete pavement is given.
