摘要
通过对不同TPS改性剂掺量的透水性沥青混合料进行短、长期老化,采用间接拉伸试验检测老化前后沥青混合料的力学性能,来评价TPS改性剂掺量对透水性沥青混合料老化性能的影响。结果表明,随着TPS掺量增加,透水性沥青混合料抗老化性能呈下降趋势。
Through the short time oven aging and the long time oven aging of porous asphalt mixtures,which have different TPS modifier content,we tested the mechanical properties of asphalt mixture before and after oven aging by using the indirect tensile test.Tests were conducted to evaluate the effect of the TPS modifier on aging resistance of porous asphalt mixtures.The results show that the properties of aging resistance of porous asphalt mixtures have a downward trend with the increasing TPS content.
