同步薄层罩面混合料设计要求有足够的空间容纳上升的乳化沥青,可见混合料的空隙率直接影响乳化沥青的喷洒量,本文研究了空隙率与乳化沥青用量之间的关系,分析得出同一种类型的沥青混合料下,乳化沥青喷洒量与混合料空隙率存在良好的线性关系,并回归出不同级配下乳化沥青用量随空隙率变化方程;为方便生产,寻找出体积法与塑封法确定空隙率之间的关系。结合实际状况,针对不同交通量与路面状况,对乳化沥青用量进行了相应的调整。
The design of the synchronous laminar cover mixture has enough space to accommodate the ascending emulsified asphalt. It can be seen that the voidage of the mixture directly affects the amount of emulsified asphalt sprayed. In this paper, the relationship between the voidage and the amount of emulsified asphalt was studied. Under the same type of asphalt mixture, there is a good linear relationship between the amount of emulsified asphalt sprayed and the voidage of the mixture, and the equation of variation of the amount of emulsified asphalt with the voidage under different gradation levels is regressed. For convenience of production, Method to determine the relationship between porosity. According to the actual situation, according to different traffic and road conditions, the amount of emulsified asphalt was adjusted accordingly.
