南京市的各式黑色道路中,表面处治很多。这些表面处治大致可分为两种类型:一种是在旧泥结碎石路面上进行表面处治,另一种是先修建泥结碎石路,开放一段时期的交通后,再进行表面处治。新的表面处治是属于后一种类型的改良,又类似简易式贯入路面。它的厚度甚薄(1(1/2)至2公分)。其优点是它的结构型式新颖,可以保证连续施工,缩短施工期限,节省人工和材料,从而降低路面的工程造价。兹将新方法的结构、所用材料、施工方法及有关含水量的掌握等问题简述如下。
Nanjing, all kinds of black roads, a lot of surface treatment. These surface treatments can be broadly divided into two types: one is surface treatment on the old clay-bonded gravel pavement, and the other is the construction of the cement-bound gravel road. After a period of open traffic, the surface treatment is performed. The new surface treatment belongs to the latter type of improvement, but also similar to simple into the road. Its thickness is very thin (1 (1/2) to 2 cm). Its advantage is its novel structure, can ensure continuous construction, shorten the construction period, saving labor and materials, thereby reducing the cost of the road construction. The structure of the new method, materials used, construction methods and mastery of the relevant water content are summarized below.
