摘要
矿质集料的粗度和形状对沥青混合料性能具有极为明显的影响,目前关于粗集料棱角性对沥青混合料性能的影响研究很少。文章采用ASTM D3398方法定量测量了7种不同粗集料的平均棱角性I,研究了粗集料平均棱角性I对沥青混合料性能的影响。结果表明,粗集料平均棱角性I对沥青混合料的高温稳定性、低温抗裂性和水稳定性均有不同程度的影响。
Coarseness and shape of mineral aggregates have great influence on hot-mix asphalt properties, At present, there is little study on the influence of coarse aggregates angularity on hot-mix asphalt properties. In the paper, ASTM D3398 method is adopted to measure average angularity I of 7 different coarse aggregates, Then the influence of coarse aggregates with average angularity I on hot-mix asphalt properties is studied. The experiment result indicates that coarse aggregates with average angtdarity I has different effect on high-temperature stability, low-temperature anti-cracking and moisture susceptibility properties of hot-mix asphalt.
