Durable old cement concrete pavement structure suitable for extra-heavy traffic grade and design method
The invention discloses an old cement concrete pavement durable structure suitable for an extra-heavy traffic grade and a design method. According to the method, an asphalt surface layer is directly paved after the old cement pavement is rubbalized, or graded broken stones are paved as a base layer, and after the old cement pavement slab and the base layer are treated firstly, granular mixtures on the rubbalized surface layer are milled off, so that the bearing performance of the old cement pavement slab can be utilized to the maximum extent; the old cement pavement rubblization lower base layer is used as the base layer, the structural attribute of the asphalt surface treatment layer is strengthened, and on the premise of improving the bearing resistance, the overall thickness of the pavement structure layer is reduced, the subsequent maintenance cost of the pavement is reduced, the maintenance efficiency is improved, and the pavement structure attribute is enriched.
本发明公开适用于特重交通等级的旧水泥混凝土路面耐久型结构及设计方法；本发明常规采用旧水泥路面碎石化后直接加铺沥青面层，或者加铺级配碎石作为基层，本发明提供的先处置旧水泥路面板及基层病害后，铣刨掉碎石化后表面层散粒体，能够最大限度利用旧水泥面板的承力性能；将旧水泥路面碎石化下基层作为基层，强化沥青表面处置层的结构属性，在提升抗承载性能的前提下，降低路面结构层整体厚度，降低路面后续养护费用，提升养护效率，丰富了路面结构属性。
