山岭重丘区因地形限制,极限纵坡较多。重载车辆,特别是手扶拖拉机,最易损坏路面。过去,对这样的路段,一般采用浆砌片石或铺砌混凝土预制块等方法,均收到一定的效果,但成本较高。近年来,为降低造价,我们利用石灰渣或拆除砖石结构的废灰浆渣拌黄泥嵌碎石效果良好。 Mountain heavy hill due to terrain restrictions, extreme longitudinal slope more. Heavy-duty vehicles, especially walking tractors, most damage the road. In the past, for such sections, generally using mortar rubble or paved concrete prefabricated blocks and other methods, have received some results, but the cost is higher. In recent years, in order to reduce the cost, we use the limestone residue or dismantle the masonry structure waste ash residue mixed with yellow mud embedded stone effect is good.
