| 摘 要： | 在试验研究的基础上，探讨了在限定级配下，由于天然砂与石屑混合组成的细集料的棱角性（FAA）对沥青混合料体积性质、水敏感性的影响。结果表明，FAA值对沥青混合料的体积指标、水敏感性有一定影响，但影响程度并未表现出显著的线性规律。FAA值不适合单独作为评价细集料品质的技术指标。

| Abstract: | By experimental study,how the moisture susceptibility and volume property was influenced by the FAA value of mixed fine aggregate which includes natural sand and stone chips was discussed.It was concluded that fine aggregate angularity influenced the moisture susceptibility and volume property in a way,but no notable linear relation to them.In addition,FAA alone may not be adequate to assess the quality of the fine aggregate. |
