Rapid reconstruction construction method for cement concrete pavement
The invention relates to a rapid reconstruction construction method for a cement concrete pavement. The rapid reconstruction construction method comprises the following steps: carrying out impact gravel construction on an old cement concrete pavement slab by using an MHB multi-hammer crusher; the method comprises the following steps: laying alkaline gravel chips on the surface of an old cement concrete pavement slab after rubblization to carry out sealing treatment, and then rolling and compacting the pavement by adopting a Z-shaped road roller; after the seal coat treatment, slow-breaking modified emulsified asphalt is laid on the alkaline gravel chips for prime coat construction, and then smooth wheel static pressure is carried out; performing transition treatment on joints of the rubblization cement concrete pavement and the non-rubblization cement concrete pavement; and the pavement treated in the fourth step is subjected to construction of a water-stable base layer and an asphalt surface layer, and rapid reconstruction construction of the cement concrete pavement is completed. According to the method, on-site crushing and one-time forming are adopted, after crushing is completed, pressing is conducted through the Z-shaped road roller, a flat and stable base layer structure is formed, the problem of reflection cracks can be solved, and the long-term stability and safety of a roadbed structure are guaranteed.
本发明涉及一种水泥混凝土路面快速改造施工方法，按以下步骤进行：用MHB多锤头破碎机对旧水泥混凝土路面板进行冲击碎石施工；对旧水泥混凝土路面板碎石化后表面铺设碱性碎石屑进行封层处理，然后采用Z型压路机对路面碾压压实；封层处理后，再在碱性碎石屑上面铺设慢裂改性乳化沥青做透层施工，然后进行光轮静压；碎石化和非碎石化水泥混凝土路面接缝进行过渡处理；对步骤四处理后的路面进行水稳基层和沥青面层的施工，完成水泥混凝土路面快速改造施工。本发明该方法采用就地破碎，一次成型，完成破碎后通过Z形压路机压稳，形成平整、稳固的基层结构，而且能解决反射裂缝问题，保证路基结构的长期稳定性与安全性。
