摘要
结合沥青混合料击实困难的工程实际问题,通过室内试验比较了辉绿岩和花岗岩碎石性质的差异,通过堆积密度试验分析了细集料矿料棱角性对合成矿料级配干涉状态、性质的影响。
Combined with actual project problems such as difficulties in tamping asphalt mixing material, the difference between diabase and granite debris via indoor experiments is compared in this paper. Through piling density experiments, influence by fine aggregate mineral angularity to gradation interference and performance of synthetic minerals analyze is also analyzed.
