摘要
结合分级掺配法和CAVF主骨料空隙填充法,根据基体混合料的目标孔隙率要求,确定了每档集料的比例,精确设计了基体混合料的级配,经试验表明,根据设计级配制作的基体沥青混合料的各项性能指标均满足要求。
Combining the multilevel mixing method and CAVF main aggregate void filling method,according to the target porosity requirements of matrix mixture,this paper determined the ratio of each set aggregate,precise designed the matrix mixture gradation,the experiments showed that each performance index of matrix asphalt mixture according to gradation design met the requirements.
