Through piling density experiments,influence by fine aggregate mineral angularity to gradation interference and performance of synthetic minerals analyze is also analyzed.
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。
By analyzing experimental data,the paper discussed how asphalt content,volume property,moisture susceptibility and rutting performance were influenced by the fine aggregate angularity( F FAA ).
通过分析试验数据 ,考察了细集料棱角性 (FFAA)对沥青混合料沥青用量、体积性质、水稳定性、高温稳定性等重要指标或性能的影响情况 。
And modified ones are proposed to compare difference of fine aggregate angularity(FAA) of three different fine aggregates,including crushed sand,chip\'s and natural sand.
探讨现行两种细集料棱角性试验方法不易操作之处,并提出改进试验方法来考察机制砂、石屑、天然砂等3种细集料的棱角性差异,发现机制砂和石屑的棱角性相近,都优于天然砂。
