Intersection road maintenance construction method and road structure thereof
The invention discloses an intersection road maintenance construction method and a road structure thereof, and the construction method comprises the following steps: prefabricating UHPC-NC composition boards, pre-burying dowel bar assemblies, splicing the UHPC-NC composition boards, laying the UHPC-NC composition boards on a road base, adjusting the elevation to form a leveling layer pouring space, and grouting and pouring. The joints between the UHPC-NC composition boards and the joints of the dowel bar assemblies are grouted and poured, and a wearing layer is paved; the road structure comprises an old road base layer, a leveling layer, a UHPC-NC composition board layer and a wearing layer which are sequentially arranged from bottom to top, and the UHPC-NC composition board layer comprises a plurality of UHPC-NC composition boards and dowel bar assemblies used for connection. According to the novel road, by means of high strength and rigidity formed after pouring combination of UHPC and NC, the protection effect on the road base is enhanced, the dowel bar assemblies are adopted to enable the UHPC-NC combined plate layers to be integrally and synergistically stressed and jointly resist the frequent starting and stopping effect of vehicle loads at the intersection, meanwhile, the thickness of a wearing layer is reasonably reduced to improve ruts, and the service life of the road base is prolonged. The UHPC is firmly connected with the wearing layer, the novel road is high in integrity and stability, and meanwhile the construction time can be effectively shortened.
本发明公开了一种交叉口道路的维修施工方法及其道路结构，施工方法包括UHPC‑NC组合板的预制和传力杆组件的预埋，拼接UHPC‑NC组合板并铺设于道路基层上，调节高程形成调平层浇筑空间并灌浆浇筑，灌浆浇筑UHPC‑NC组合板之间的接缝和传力杆组件接缝，摊铺磨耗层；道路结构包括从下至上依次设置的旧道路基层、调平层、UHPC‑NC组合板层和磨耗层，UHPC‑NC组合板层包括若干块UHPC‑NC组合板和用于连接的传力杆组件。本发明公开的新型道路凭借UHPC与NC浇筑组合后形成的较高的强度与刚度，加强了对道路基层的保护效果，采用传力杆组件使UHPC‑NC组合板层整体协同受力，共同抵抗交叉口车辆荷载的频繁启停作用，同时合理降低磨耗层厚度来改善车辙的发生，UHPC与磨耗层连接牢固，本新型道路整体性和稳定性强，同时可有效缩短施工时间。
