摘　　要：根据对70#沥青及SBS改性沥青混合料掺加0.25%博尼维纤维后的试验,对比分析了70#沥青混混合料、SBS改性沥青混合料、掺加纤维的70#沥青混合料和掺加纤维的SBS改性沥青混合料的高温稳定性和低温抗裂性能。结果表明,SBS改性沥青的车辙因子远高于70#沥青胶结料,应用SBS改性沥青和博尼维纤维能够大幅提高混合料的高温性能,对其他路用性能也有一定改善,博尼维纤维具有良好的推广价值。In this paper, laboratory tests were carried out to investigate the road performance （high temperature stability, water stability, and low temperature crack- resistance performance） of AC- 16 mixtures with different asphalts and the 0.25% Bonifibers. It is indicated that the G ＊/sinδ indices of SBS modified asphalt at 50℃ and 60℃are far greater than the 70^# asphalt, so the high temperature stability will be improved distinctly by using SBS modified asphalt and the other road performances can also be enhanced in some sort; the Bonifibers can improve the road performance of mixture, and has a excellent application value.
