旧路路面结构改造的研究

Research on Reconstruction of Pavement Structure of Old Road

伴随我国城市的扩张及快速发展,道路交通流量的增加,城市道路运营临近或者超过路面设计基准期,城乡公路的市政化改造,现阶段我国老旧道路路面改造问题突出。为有效地解决旧路路面结构改造问题,结合现状路面结构、路面病害调查、交通流量、道路周边边界控制条件等控制因素,分别针对现状水泥混凝土路面改造加铺沥青混凝土,现状沥青混凝土路面改造加铺沥青混凝土进行研究,提出了不同适用条件下的路面结构加铺方案。

With the urban expansion and rapid development of China, the road traffic flow increases, and the urban road operation approaches or exceeds the design reference period of pavement, and at the present stage, the problems existing in the municipal reconstruction of urban and rural highways, and the pavement reconstruction of old road are serious in China. In order effectively solve the reconstruction problem of old road pavement structure, and according to the control factors of present pavement structure, pavement disease survey, traffic flow, and control conditions on boundary of road, the article studies the overlay of asphalt concrete on the present cement concrete pavement and the overlay of asphalt concrete on the present asphalt concrete pavement, and puts forward the pavement structure overlay schemes under the different application conditions.
