从1962年开始,我们在北京市郊区公路上学习使用道路渣油做了一些表面处治(以下简称渣油表面处治)工程。这些渣油表面处治下的路面是结合原路面情况和养护大中修的需要来决定做法的,有在原路面上直接泼油的;有在原路面上做碎石整平层或加料辗压保养整平的;有用机械豁松原路面加骨料或石灰调整水稳定性和平整度;有结合处治翻浆加铺石灰土路面和为了补足强度而加铺石灰土、碎石路面等。渣油表面处治所用的材料也是比较复杂的,渣油稠度相差很悬殊,标准稠度从5～160秒。根据就地取材的原则,我们所用的矿料有软硬不同,级配长短不同的砾石和碎石。采用的施工方法,绝大部分是先泼油,后撒料两次喷油的单层处治。现在看来,我们所做的渣油表面
Since 1962, we have been studying the use of road residual oil on the suburb of Beijing to do some surface treatment (hereinafter referred to as the “Resurfacing” project). The surface treatment of these residual oil surface is combined with the original road conditions and maintenance of large and medium-sized repair needs to decide on the practice, there are directly on the original surface of the spilled oil; there are in the original road gravel leveling or feeding rolling maintenance Flat; useful mechanical loose slab pavement aggregate or lime to adjust the water stability and flatness; a combination of treatment of rake plus limestone soil pavement and in order to make up for strength and add lime soil, gravel road. Residue surface treatment material is also more complex, residual consistency difference is very poor, the standard consistency from 5 to 160 seconds. According to the principle of using local materials, the mineral materials we use are different in hardness and grading, graded gravel and gravel with different grading. The construction methods used, the vast majority of the first oil spill, sprinkled twice after injection of single-layer treatment. It now appears that we have made the surface of the residue
