摘要
本文系统地介绍了聚乙烯改性沥青的室内试验研究结果。低密度聚乙烯具有较好的改性效果。改性后的沥青及其混合料的路用性能皆比基础沥青的好。并对聚乙烯的改性机理作了初步探讨。
In this paper,authors systematically introduce the result of the test and study for polythene modified asphalt in laboratory. It shows that the low-density polythenen has better improved effects. Because the pavement performance of the polythene modified asphalt and its mixes is better than that of the raw asphalt. And also,probe into the modified mechanism of polythene.
