Abstract:

为研究高模量、高黏沥青老化前后动态力学流变特性,优化性能评价指标,利用动态剪切流变仪(DSR)和弯曲梁流变仪(BBR)对原样、RTFOT和PAV沥青进行了黏弹性能、抗车辙性能、抗疲劳性能及抗裂性能测试.结果表明储能模量G'、损耗因子tanδ以及延迟弹性恢复指标εp/εL能够准确评价不同类型沥青老化前后力学性能,其中高模量沥青抗车辙能力和延迟恢复抗变形能力最佳,而高黏沥青抗疲劳和低温抗裂能力最优;但沥青抗老化能力基于不同力学流变指标的分析结果而异,对低温指标,高黏沥青优于高模量沥青,中、高温指标则相反.总之,对高模量、高黏等特征性显著的沥青建议选择合理试验参数,增加PAV或延长老化等作用条件,结合主导因素指标进行综合评价.
