Ecological high-strength cement concrete pavement compaction forming method
The invention provides a compaction forming method for an ecological high-strength cement concrete pavement. The compaction forming method mainly comprises the following steps: step 1, determining a standard theoretical density through calculation; 2, the target compaction degree of rolling is determined through an axis compressive strength test; 3, the compaction work needed in the indoor test piece forming process is calculated by fitting a pressure-displacement relation curve in the test piece forming process and integrating; 4, calculating the tonnage number of a road roller adopted for road surface field rolling according to the unit density change compaction work equivalent relation; step 5, determining the rolling times of the road roller through on-site concrete trial paving; and 6, after paving and rolling are completed, epoxy resin super glue and a protection agent are sprayed on the surface of the road surface. According to the method, full-mechanical paving and rolling control is carried out on the ecological high-strength cement concrete pavement, quantitative compaction control indexes and an integrated construction process can be determined, and the high strength of the concrete pavement is guaranteed.
本发明提出了一种生态型高强水泥混凝土路面压实成型方法，主要包含：步骤一，通过计算确定标准理论密度；步骤二，通过轴心抗压强度试验确定碾压的目标压实度；步骤三，通过拟合试件成型过程中的压力—位移关系曲线并积分，计算室内试件成型过程中所需的压实功；步骤四，通过单位密度变化压实功等效关系，计算路面现场碾压采用的压路机的吨位数；步骤五，通过现场混凝土试铺确定压路机碾压遍数；步骤六，摊铺碾压完成后，在路面表面喷涂环氧树脂强力胶保以及护剂。本发明的方法对生态型高强水泥混凝土路面进行全机械化摊铺碾压控制，可以确定量化的压实控制指标以及集成化的施工工艺，保证混凝土路面的高强度。
