【摘要】 为了克服普通沥青混凝土性能的缺陷,提高沥青混凝土的性能,通常在沥青混凝土中掺入路用纤维。本文通过试验分析,探讨了相关的作用机理。结果表明,路用纤维加入后,沥青混合料的最佳油石比有所增加,密度有所降低,空隙率略有增加;并可较好地提高沥青混合料的马歇尔稳定度、水稳定性、高温稳定性以及低温抗裂性。更多还原

【Abstract】 To avoid the defects of the ordinary asphalt concrete (OAC) and promote the performance,the performance of fibre reinforced asphalt concrete (FRAC) has been tested and the corresponding mechanism has been analyzed.The results show that in comparison with OAC,the optimum asphalt content and percentage of voids of FRAC increase slightly while the density reduces, and that the Marshall stability, moisture stability, high temperature stability and anti-cracking resistance at low temperature of FRAC are greatly improved.更多还原
