| 摘 要： | 采用多层共挤膜废料(r-MCEFS)对重交70#沥青进行改性制备r-MCEFS改性沥青。探讨了r-MCEFS用量对改性沥青的常规性能、微观结构和流变性能的影响。结果表明,随着r-MCEFS用量的增加,基质沥青的软化点逐渐上升；当r-MCEFS用量增加到4份（质量份数,下同）后,改性沥青的相形态由“海-岛”结构逐渐转变为“类网络”结构；随着r-MCEFS用量的增加，改性沥青的回弹模量和高温稳定性得到改善，r-MCEFS与沥青基质的界面作用增强。

Microstructure and Rheological Behavior of Recycled Multilayer Co-extrusion Film Scraps Modified Asphalt |
| |
| Abstract: | The recycled co extrusion multilayer film scraps(r-MCEFS) were employed to modify asphalt(heavy traffic 70#). The effect of r-MCEFS dosage on the general performances, microstructure, and rheological property of the modified asphalt were investigated. It showed that the softening point of the modified asphalt increased with increasing r-MCEFS content. The microstructure of the modified asphalt converted from the “sea-island” into the “web-like” structure at 4 phr r-MCEFS content. The elastic recovery and high temperature stability were improved by the introduction of r-MCEFS. Interfacial interaction between asphalt and r-MCEFS was increased. |
