【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。更多还原

【Abstract】 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.更多还原
