摘　　要：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 .结果表明 ,FFAA均未与上述指标或性能建立起显著的线性关系 .FFAA不适合单独作为评价细集料品质的技术指标 。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 ).The conclusion was drawn that there are no notable linear relation between fine aggregate angularity and each of the above-mentioned properties.In addition, F FAA alone may not be adequate to assess the quality of the fine aggregate.
