Combined type widening transformation base layer based on old road pavement and construction method
The invention relates to an old road pavement-based combined type widening transformation base layer and a construction method, and relates to the technical field of pavement transformation. The combined type widening transformation base layer comprises an old road and a new road, the old road and the new road are jointly paved with an asphalt surface layer, the new road comprises a widening base layer flush with the old road pavement, a concrete sleeper beam is poured below the widening base layer and extends to the position below the old road pavement structure layer, and embedded steel bars are arranged on the longitudinal side edges of the old road and transversely extend into the widening base layer. The method has the effects that: the connectivity of the widened base layer and the old road is improved, the overall stress of the reconstructed and expanded road surface is ensured, and differential settlement of the road surface is reduced.
本申请涉及一种基于旧道路路面的组合式拼宽改造基层及施工工法，涉及路面改造的技术领域，其组合式拼宽改造基层包括旧道路和新道路，所述旧道路和新道路上共同铺设有沥青面层，所述新道路包括与旧道路路面平齐的拼宽基层，所述拼宽基层的下方浇筑有混凝土枕梁，所述混凝土枕梁延伸至旧道路路面结构层下方，所述旧道路纵向侧边设有植筋，所述植筋横向延伸至拼宽基层内。本申请具有提高拼宽基层与旧路的连接性，确保改扩建后路面的整体受力，减小路面的不均匀沉降的效果。
