包装废PE改性沥青的研究

Analysis of Modified Asphalt by the Waste-PE in Packaging

利用包装废弃物(PE)对沥青进行改性,提高沥青综合性能,同时解决了包装废PE回收利用和沥青性能达不到实际应用要求的问题,试验测得沥青的软化点提高;延伸度、降低针入度,并针对试验结果进行理论分析,研究聚合物(PE)改性机理,有极强的现实意义。

A method to modify asphalt by making use of the wastePE in packing was provided, to improve the comprehensive performance of the asphalt. A solution to the problem of waste packing callback and the problem that the asphalt function cannot meet the practical requirement was also provided. The result of experiment showed it enhanced the asphalt's softening point,decreased the penetration and extension ability .The experiment results and the mechanism of the modification were analyzed.
