无论是在沥青混合料配合比组成设计中,还是在沥青路面施工质量控制过程中,集料毛体积相对密度测定的准确与否,直接关系到沥青混合料的空隙率(VV)、矿料间隙率(VMA)、饱和度(VFA)等沥青混合料体积指标能否满足要求。而在集料毛体积相对密度测定中,细集料毛体积相对密度的测定,具有相当大的难度,对试验人员的操作水平要求相对较高。 Whether it is in asphalt mix design, or in asphalt pavement construction quality control, the accuracy of aggregate density measurement is directly related to asphalt mixture voids (VV), mineral aggregate clearance Rate (VMA), saturation (VFA) and other asphalt mixture volume index can meet the requirements. In aggregate gross volume relative density determination, fine aggregate gross volume relative density determination, with considerable difficulty, the operator of the relatively high level of operational requirements.
