Highway reconstruction and extension spliced road structure in hot and humid areas and construction method
The invention relates to the technical field of highway engineering construction, in particular to an expressway reconstruction and extension spliced road structure in hot and humid areas and a construction method.The structure comprises an old road surface, a new road surface and a drainage facility, and the new road surface sequentially comprises a new surface layer, an anti-fatigue layer, a new water stable base layer, a new water stable subbase layer and a graded broken stone hardcore from top to bottom; the drainage facilities are arranged on the top face of the junction of the old water stable base layer and the new water stable base layer and the top face of the junction of the old water stable subbase layer and the new water stable subbase layer, and drainage pipes extending to the outer side of the new road surface are connected to the drainage facilities. According to the highway reconstruction and extension spliced road structure in the hot and humid areas, the problems that a traditional spliced structure of a highway reconstruction and extension project in the hot and humid areas is unsmooth in internal drainage, rut diseases are prone to occurring at high temperature, reflection cracks are serious, and stress of new and old road structures is not coordinated are solved; and the overall durability of the highway reconstruction and extension spliced road structure is greatly improved.
本发明涉及公路工程建设技术领域，具体是一种湿热地区高速公路改扩建拼接道路结构及施工方法，结构包括旧路面、新路面和排水设施，新路面自上至下依次为新面层、抗疲劳层、新水稳基层、新水稳底基层和级配碎石垫层；排水设施设置在旧水稳基层与新水稳基层交界处的顶面和旧水稳底基层与新水稳底基层交界处的顶面，排水设施上连接有延伸至新路面外侧的排水管。本发明提供的湿热地区高速公路改扩建拼接道路结构解决了湿热地区高速公路改扩建工程传统拼接结构内部排水不畅、高温下易出现车辙病害、反射裂缝严重、新老路结构受力不协调等问题，大大提升了高速公路改扩建拼接道路结构的整体耐久性。
