复合改性沥青的性能评价与验证

Evaluation, Test and Verification on Performances of Compos ite Modified Asphalt

采用了3种评价方法与指标,对一种新型复合改性沥青高温稳定性、低温性能、热存贮性能等路用性能进行了研究与评价,对其实验结果进行了对比与分析,研究结果表明复合改性沥青综合性能良好,尤其在高温稳定性方面性能优异,铺筑的试验路进一步证明复合改性沥青的优异性能。

With various evaluation methods and indexes,road performances such as stability in high temperature and in low temperature,thermal storage etc for a new type of composite modified asphalt have been studied and evaluated,and the tested results have been compared and analyzed.The study results show that the comprehensive performances of composite modified asphalt are good,especially on stability in high temperature.And the results of performances of composite modified asphalt taken from a testing road verify the effectiveness of the evaluation results taken from laboratory.
