New and old concrete pavement splicing structure suitable for white-plus-black pavement and construction method
The invention provides a new and old concrete pavement splicing structure suitable for a white-plus-black pavement and a construction method. The splicing structure comprises sleeper beams, pavement structure layers and splicing belt pull rods, and the pavement structure layers comprise a new pavement structure layer and an old pavement structure layer; the old road pavement structure layer comprises an asphalt pavement I, a concrete upper base layer I, a water-stable lower base layer I and a water-stable subbase layer I. The new road pavement structure layer comprises an asphalt pavement II, a concrete upper base layer II, a water-stable lower base layer II and a water-stable subbase layer II. The sleeper beams are arranged at the bottom of a longitudinal joint of a new and old concrete pavement between the concrete upper base layer I and the concrete upper base layer II, and the splicing belt pull rods are arranged in the middle of the concrete upper base layer I and the concrete upper base layer II. According to the invention, the splicing structure is applied to construction for the expansion road on the white-plus-black road surface. The sleeper beams and the splicing belt pull rods are arranged, so that the pavement is protected during differential settlement of new and old pavements, longitudinal cracking is avoided, the safety of vehicles passing through the pavement is ensured, and the road maintenance cost is reduced.
本发明提供适用于白加黑路面的新旧混凝土路面拼接结构和施工方法，拼接结构包括枕梁、路面结构层和拼接带拉杆，所述路面结构层包括新路路面结构层和旧路路面结构层，旧路路面结构层包括沥青路面Ⅰ、混凝土上基层Ⅰ、水稳下基层Ⅰ、水稳底基层Ⅰ，新路路面结构层包括沥青路面Ⅱ、混凝土上基层Ⅱ、水稳下基层Ⅱ、水稳底基层Ⅱ，所述枕梁设置在混凝土上基层Ⅰ和混凝土上基层Ⅱ之间的新旧混凝土路面纵向接缝的底部，所述拼接带拉杆设置在混凝土上基层Ⅰ和混凝土上基层Ⅱ的中部。本发明用于白加黑路面扩建公路施工中，通过设置枕梁、拼接带拉杆，保证新旧路面在不均匀沉降时对路面进行保护，不产生纵向开裂，确保路面通行车辆安全，降低公路养护成本。
