This paper is oriented to appraise high, intermediate, and low temperature related performance of elastomeric and plastomeric binders and mixtures in order to evaluate their characteristics at various levels of environmental and loading conditions. Artificial oxidative hardening of asphalt binders and mixes was performed in the laboratory using short- and long-term aging protocols.At the binder level, the elastomers (styrene-butadiene-styrene (SBS) and rubber) and plastomer (ethylene-vinyl acetate (EVA)) materials improved high and intermediate temperature performance indices (G*/sin(δ) and G*.sin(δ), respectively). Interestingly, the aged SBS/bitumen blend had improved low-temperature cracking resistance compared to unaged counterpart. With the progress of oxidative hardening, the plastomer based binder did not show obvious change in the low-temperature cracking susceptibility compared to elastomer-modified binder. Seemingly, in the case of plastomer/bitumen blend, the propensity to low-temperature cracking is to a great extent controlled by the corresponding base bitumen. The plastomer based mixture had improved permanent deformation performance, whereas the elastomers afforded a tangible amelioration for the vulnerability to load and non-load associated cracking. The SBS based mixture showed highest low-temperature fracture energy compared to the EVA based mixture. Despite the determinantal effect of age-hardening to low and intermediate temperature-related cracking of mixes, the results confirmed that the elastomeric materials can retard the impact of aging level on the low temperature and fatigue cracking. Comparision of results was justified by the statistical analysis in order to determine the significance of bituminous material parameters on the measured properties.

本文旨在评估弹性体和塑性体粘合剂及混合物的高温、中温和低温相关性能，以评估它们在各种环境和负载条件下的特性。在实验室中使用短期和长期老化方案对沥青粘合剂和混合料进行人工氧化硬化。在粘合剂级别，弹性体（苯乙烯-丁二烯-苯乙烯（SBS）和橡胶）和塑性体（乙烯-醋酸乙烯酯（ EVA)) 材料提高了高温和中温性能指数（分别为 G*/sin(δ) 和 G*.sin(δ)）。有趣的是，与未老化的对应物相比，老化的 SBS/沥青混合物具有更高的低温抗裂性。随着氧化硬化的进行，与弹性体改性的粘合剂相比，基于塑性体的粘合剂在低温开裂敏感性方面没有表现出明显的变化。从表面上看，在塑性体/沥青混合物的情况下，低温开裂的倾向在很大程度上受相应基础沥青的控制。基于塑性体的混合物具有改进的永久变形性能，而弹性体为负载和非负载相关开裂的脆弱性提供了切实的改善。与基于 EVA 的混合物相比，基于 SBS 的混合物表现出最高的低温断裂能。尽管时效硬化对混合物的中低温相关开裂有决定性影响，但结果证实弹性体材料可以延缓时效水平对低温和疲劳开裂的影响。
