随着工农业生产的发展,江苏省公路局所辖主要干线,行车密度显著增加,现有路面的级配磨耗层,由于其本身存在着经过车轮作用所产生的磨损粒料细化现象,以及受到车轮与气候的双重作用,所产生的塑性指数衰化与变形现象的缺点。在行车密度较大的路段上,级配磨耗层便显得不胜负担,需要配备足够的力量进行经常性的仔细的保护,并且不断的需要配备养路材料,作为日常保养的添加料。因此养路基层单位的大部力量为维护路面表面的平整,化费了很多养路备料的采运工 With the development of industrial and agricultural production, the main trunk lines under the jurisdiction of Jiangsu Provincial Highway Bureau have significantly increased the driving density. The graded wearing layer of the existing pavement is subject to wear and tear due to its own wheel refining phenomenon, The dual role of the wheel and the climate, the resulting plastic index degradation and deformation of the shortcomings. In the road sections with greater traffic density, gradation wear layer will become too boring, you need to be equipped with enough power for regular and careful protection, and constantly need to be equipped with road maintenance materials, as routine maintenance of the added material. Therefore, most units of road maintenance grassroots units in order to maintain the smoothness of the pavement surface, the cost of a lot of road maintenance materials mining
