黑龙江省自1963年以来,运用国产道路渣油(以下简称渣油)在低级和中级路面上铺筑一部分碎砾石渣油表面处治,取得了一定的技术经验。但由于碎石或砾石在无沙石地区须外运,是不经济的。因此使用当地土壤铺筑渣油土路面是不产砂石地区的途径。笔者仅就1963、1964两年参加渣油土的施工和试验的点滴体会介绍如下: 一、渣油土的技术性质渣油土是渣油与就地土壤拌和后所得到的修筑路面材料的一种;具有隔水、灭尘等优点。由于施工气温、施工方法和所采用渣油的粘度不同,制备渣油土也应分为热拌和冷拌两个类型。渣油土的剂量选择、物理力学试验项目的依据,
Since 1963, Heilongjiang Province has made some technical experience in using the domestic road residue (hereinafter referred to as “residual oil”) to treat part of surface treatment of gravel residue on low and intermediate road surfaces. However, it is uneconomical because gravel or gravel has to be expelled in sandless areas. Therefore, the use of local soil paving the residue soil pavement is not sand gravel area approach. The author only 1963,1964 two years to participate in the construction and testing of residual oil soil bit by bit experience described below: First, the technical properties of the residue soil Residue soil is the residual oil and on-site soil after mixing the resulting pavement material Species; with water, dust and other advantages. Due to the construction temperature, construction methods and the viscosity of residual oil used in the preparation of residue should also be divided into two types of hot mix and cold mix. Residue soil dose selection, physics and mechanics test project basis,
