The main concept of using waste and recycled materials as modifiers for construction materials, is to improve their performance, keep the resources, and conserve the environment from pollution problems. This investigation is tended to evaluate the effect of using two different types of modifiers on the physical properties of asphalt binder. The modifiers are Recycled-Low-Density-Polyethylene (R-LDPE) polymer and waste-Paper Fiber (w-PF), they were mixed individually and collectively with neat asphalt binder. The first set of modified binders comprised neat binder with 3% R-LDPE alone, the second is comprised 0.3%, 0.5% and 0.7% of w-PF alone, while the third comprised collective modifiers of 3% R-LDPE and 0.3%, 0.5% and 0.7% w-PF. The influence of these modifiers on neat asphalt binder was evaluated in terms of penetration (Pen.), softening point (SP), penetration index (PI), ductility, rotational viscosity (RV), penetration aging index (PAI) and softening point index (SPI). The obtained results indicate that the utilization of modifiers helps in improving the physical properties of asphalt binders by different levels. the modification by collective modifiers leads to an increase SP, RV, PI, PAI, and SPI to 65%, 2 times, 1.044, 0.93, 2.5 respectively compared to neat bitumen. As well, leads to a decrease in both Pen. and ductility to the levels 45% and 79% respectively. This indicates that the use of waste and recycled modifiers especially in the combined form encourage the production of comparative modified asphalt binder.

评估包含废纸纤维和回收低密度聚乙烯的改性沥青粘合剂

使用废弃和回收材料作为建筑材料的改性剂的主要概念是提高其性能、保护资源和保护环境免受污染问题。本研究倾向于评估使用两种不同类型的改性剂对沥青结合料物理性能的影响。改性剂是回收低密度聚乙烯 (R-LDPE) 聚合物和废纸纤维 (w-PF),它们分别与纯沥青粘合剂混合。第一组改性粘合剂包含仅含 3% R-LDPE 的纯粘合剂,第二组仅包含 0.3%、0.5% 和 0.7% 的 w-PF,而第三组包含 3% R-LDPE 和 0.3% 的集体改性剂, 0.5% 和 0.7% w-PF。这些改性剂对纯沥青结合料的影响根据渗透率 (Pen.) 进行评估,软化点(SP)、针入度指数(PI)、延展性、旋转粘度(RV)、针入度老化指数(PAI)和软化点指数(SPI)。结果表明,改性剂的使用有助于不同程度地改善沥青结合料的物理性能。与纯沥青相比,集体改性剂的改性导致 SP、RV、PI、PAI 和 SPI 分别增加到 65%、2 倍、1.044、0.93、2.5。同样,导致两个 Pen 的减少。和延展性分别达到 45% 和 79%。这表明使用废弃的和回收的改性剂,特别是组合形式,促进了对比改性沥青粘合剂的生产。结果表明,改性剂的使用有助于不同程度地改善沥青结合料的物理性能。与纯沥青相比,集体改性剂的改性导致 SP、RV、PI、PAI 和 SPI 分别增加到 65%、2 倍、1.044、0.93、2.5。同样,导致两个 Pen 的减少。和延展性分别达到 45% 和 79%。这表明使用废弃的和回收的改性剂,特别是组合形式,促进了对比改性沥青粘合剂的生产。结果表明,改性剂的使用有助于不同程度地改善沥青结合料的物理性能。与纯沥青相比,集体改性剂的改性导致 SP、RV、PI、PAI 和 SPI 分别增加到 65%、2 倍、1.044、0.93、2.5。同样,导致两个 Pen 的减少。和延展性分别达到 45% 和 79%。这表明使用废弃的和回收的改性剂,特别是组合形式,促进了对比改性沥青粘合剂的生产。导致两者 Pen 的减少。和延展性分别达到 45% 和 79%。这表明使用废弃的和回收的改性剂,特别是组合形式,促进了对比改性沥青粘合剂的生产。导致两者 Pen 的减少。和延展性分别达到 45% 和 79%。这表明使用废弃的和回收的改性剂,特别是组合形式,促进了对比改性沥青粘合剂的生产。
