Road construction method for preventing winter cracks of northern pavement
The invention provides a road construction method for preventing winter cracks of a northern road surface, and aims to solve the problem of winter cracks of the northern road surface. The method is characterized by firstly paving a lower layer, namely a common concrete layer; secondly, when the common concrete layer is initially set, a ladder-shaped cutting frame is used for cutting the common concrete layer in a downward pressing mode, according to the ladder-shaped cutting frame, a set of cutters are installed between two parallel frames, all the cutters are parallel to each other and are in a transverse grid shape, the thickness of each cutter is 2 mm, and the distance between every two adjacent cutters is 2 m; thirdly, the ladder-shaped cutting frame is lifted to be away from the common concrete layer, the cutter leaves transverse type gaps in the common concrete layer, and the width of each gap is 2 mm; and finally, after the common concrete layer is finally set, paving asphalt concrete, namely a pavement layer, on the common concrete layer.
本发明提供一种防止北方路面冬季裂缝的道路施工方法，要解决的问题是：北方路面冬季裂缝。其要点是：首先铺设下层即普通混凝土层；其次当普通混凝土层初凝时使用梯子形切割架以下压方式对普通混凝土层进行切割，所述梯子形切割架是指，在两个平行的边框之间安装一组切刀，所有切刀相互平行呈横格状，每个切刀的厚度为2毫米，相邻两个切刀的距离为2米；再次是抬起梯子形切割架使之离开普通混凝土层，切刀在普通混凝土层上留下了横格式缝隙，每个缝隙的宽度为2毫米；最后是当普通混凝土层终凝后，在普通混凝土层铺设沥青混凝土即路面层。
