Cement pavement construction process based on road construction in-situ recycled water-stabilized base structure
The invention discloses a cement pavement construction process based on a road construction in-situ recycled water-stabilized base structure in the technical field of road construction, which comprises the following construction steps of: firstly, pretreating an old cement pavement, then crushing a cement slab for the first time, then crushing the cement slab for the second time, and finally crushing the cement slab for the second time; and then completing the construction of the gravel water-stable layer grading material: adopting a cold regeneration unit, spreading cement, mixing, strickling and rolling to complete the construction of the gravel water-stable layer, and finally paving an asphalt surface layer 7-9 days after the completion of the construction of the gravel water-stable layer, which is the same as the conventional cement-stabilized gravel layer, so as to complete the construction of the gravel water-stable layer. According to the technology, a crushing machine is adopted to crush the cement pavement on site, the original cement pavement can be crushed into particles with small particle sizes, then a certain amount of stabilizer is added on site to form a mixture with certain pavement performance, and the mixture is shaped, rolled and cured to form a pavement structure layer.
本发明公开了道路施工技术领域的基于道路施工就地再生水稳基层结构的水泥路面施工工艺，该工艺施工步骤：首先旧水泥路面预处理，然后对水泥板进行第一次破碎，接着对水泥板进行第二次破碎，然后完成碎石水稳层级配材料施工：采用冷再生机组，撒布水泥，拌和、刮平、碾压，完成碎石水稳层施工，最后与常规的水泥稳定碎石层相同，在完成碎石水稳层施工后的7‑9天就可以摊铺沥青面层，本发明水泥砼路面就地再生水稳基层结构技术是采用破碎机械就地破碎水泥路面，原水泥路面可破碎成具有较小粒径颗粒，然后再现场添加一定量的稳定剂形成具有一定路用性能的混合料，经整形、碾压和养生，并成为路面结构层的工艺。
