随着硬性面层道路建设工程量的不断增加和胶结料及石料的需要量越来越多,同时也增加了现有道路的养护、维修费用.据有关资料统计,这些费用占道路建设开支的60%以上.开支的大部分用于材料费支出.所以,改进现有路面维修方法,降低路面维修材料用量,仍是迫切需要解决的问题.传统的沥青砼路面维修的方法是:先用机械挖掉破损路面上的材料,清除表面杂物,打好底层,然后摊铺新沥青砼,接着整平表面并将其压实.这一维修方法的缺点是
With the increasing amount of hard surface road construction works and the increasing demand of cementitious materials and stone materials, as well as the cost of maintenance and repair of existing roads, according to statistics, these costs account for 60% of the expenditure on road construction %. Expenses are mostly spent on material expenses.So, to improve the existing pavement maintenance methods and reduce the amount of pavement maintenance materials is still an urgent need to solve the problem.Traditional asphalt concrete pavement maintenance method is: first with mechanical digging Get rid of damaged materials on the pavement, clear the surface debris, lay the bottom, and then paving the new asphalt concrete, and then leveling the surface and compaction. The drawback of this maintenance method is
