摘要:
为了定量评价矿料分异处理对路面抗滑性能的改善效果,选择石灰岩和玄武岩2种抗磨性能差异较大的矿料做分异处理,建立了平均衰变速率(ADR)和平均波动幅度(AAF)2个指标,分别用来表征抗滑性能的衰减速率和波动剧烈程度.同时,基于ADR和AAF进一步定量分析了不同分异配比值对抗滑性能的影响.结果表明,分异化处理能够改善沥青路面的抗滑性能,加剧抗滑性能波动的剧烈程度,降低抗滑性能的衰变速率,延缓其衰变进程.但不同分异配比值对抗滑性能的影响截然不同,合理选择分异配比值,可以降低抗滑性能的衰减速率,生成新的纹理构造,从而显著地改善混合料的抗滑性能.
Abstract:
In order to quantitatively evaluate the effect of differentiation processing on pavement sliding resistance, two types of mineral aggregates with different wear resistances, limestone and basalt, were chosen for differentiation processing, and average decay rate(ADR)and average amplitude of fluctuation(AAF)were established to express the degradation rate and the fluctuation amplitude, respectively. Additionally, based on ADR and AAF, the effect of differentiation distribution ratios on sliding resistance was also analyzed. The results show that the differentiation processing of mineral aggregate can improve the pavement sliding resistance, intensify the fluctuation intensity and delay the degradation process. However, the influence of different differentiation distribution ratios on sliding resistance is completely different. The reasonable choice of differentiation distribution ratio is helpful to decrease the degradation rate of sliding resistance and generate new texture structures, thus improving the sliding resistance of asphalt mixture.
