摘要:
采用弯拉应变作为剑麻纤维高模量沥青混合料低温性能的评价指标,考察了剑麻纤维长度及其掺量对高模量沥青混合料低温性能的影响. 同时,对剑麻纤维高模量沥青混合料的高温性能和水稳定性进行了验证. 结果表明,在剑麻纤维掺量为0. 3%条件下,纤维长度能够明显影响弯拉应变值;其中6 mm长的剑麻纤维对高模量沥青混合料的弯拉应变值比不掺加剑麻纤维的高模量沥青混合料增幅高达123%. 在剑麻纤维长度为6 mm的条件下,弯拉应变值随着剑麻纤维掺量的增大呈现出先增大后减小的变化趋势;其中0.3%掺量的剑麻纤维对高模量沥青混合料低温性能改善效果最为突出. 此外,剑麻纤维的添加对高模量沥青混合料的高温和水稳定性能均有一定程度提升.
Abstract:
The influences of the length and mass fraction of sisal fiber on the low temperature performance of high modulus asphalt mixture (HMAM) were investigated by selecting the bending strain as the evaluation index,and the high temperature performance and water stability of HMAM of sisal fiber were also explored. The results demonstrate that the bending strain of the HMAM was significantly affected by the fiber lengths when the mass fraction of sisal fiber keeps at 0.3%, and it increases by 123% compared to that with no sisal fiber as the length of sisal fiber is 6 mm. The bending strain of HMAM increases first and then decreases with the mass fraction of sisal fiber increasing when the length of sisal fiber keeps at 6 mm, and the sisal fiber with mass fraction of 0.3% possesses the best enhancement effect on the low temperature performance of HMAM. We also find that the sisal fiber can improve the performance of high temperature and water stability of the HMAM.
