Construction method for transforming cement pavement
The invention discloses a construction method for transforming a cement pavement, which comprises the following steps: (1) crushing a cement layer, and excavating to the top surface of a roadbed; (2) vertical cutting and grooving are carried out; (3) a plurality of steel pipes obliquely inserted into the roadbed are evenly distributed in the vertical cutting open grooves; (4) transverse and longitudinal steel bars are arranged in the vertical cutting grooves; (5) pouring new concrete into the steel pipes and the vertical cutting slots to form a bottom surface layer of the modified cement pavement; (6) laying a middle transition layer on the bottom surface layer; and (7) asphalt concrete is poured on the middle transition layer, and a top surface layer of the modified cement pavement is formed. Cracks caused by differential settlement of the joint of the new pavement and the old pavement are effectively prevented, settlement is inhibited, stress distribution is uniform, the overall strength of the pavement structure is enhanced, the deformation resistance and the tension resistance of the pavement are enhanced, and the overall use performance and the bearing capacity of a road are enhanced.
本发明公开了一种改造水泥路面的施工方法，包括以下步骤：(1)水泥层破碎，并挖除至路基顶面；(2)进行竖向切割开槽；(3)在竖向切割开槽内均布斜插入路基的多根钢管；(4)在竖向切割开槽内布置横向和纵向钢筋；(5)向钢管内和竖向切割开槽内浇筑新混凝土，形成改造水泥路面的底面层；(6)在底面层上铺设中间过渡层；(7)在中间过渡层上浇筑沥青混凝土，形成改造水泥路面的顶面层。本发明有效地防治新老路面结合部不均匀沉降而造成的裂纹，并且抑制沉降，均匀应力分布，增强了路面结构整体强度，加强了路面的抗变形和抗拉能力，增强了公路的整体使用性能和承载能力。
