摘要
通过对大连太平洋基质沥青、SBS改性后的改性沥青及分别在这两种沥青中加博尼维聚酯纤维得到四种沥青种类,在同一矿料级配和确定最佳沥青用量条件下所形成四种沥青混合料进行低温弯曲蠕变、间接拉伸室内试验得到的代表低温性能参数对比分析,并对4种沥青混合料的低温抗裂性能作出评价,来检验这4种沥青混合料在寒区高等级路面应用效果,为今后工程沥青路面设计对沥青混合料选用提供参考。
The four kinds of asphalt mixtures namely pacific base asphalt of Dalian City, SBS polymer modified asphalt, and the above both mixed with BoniFiber polyester fiber were used to conduct low temperature bending creep test and indoor indirect tension test under the circumstance of the same mineral aggregate gradation and determined optimum asphalt content. Then the low temperature performance parameters obtained from the test were compared and analyzed and the low temperature anti-cracking performance of the four asphalt mixtures was evaluated to examine their application effect in the cold region high grade pavement and further to provide reference for the choice of asphalt mixture in the design of asphalt pavement in the future
