Abstract: This paper investigates the effects of prolonged high-temperature storage on thermal stability, rutting, and fatigue resistance of different pure and modified binders: pure bitumen (PB), used engine oil-modified bitumen (UEOmB), plastic bag waste-modified bitumen (WPmB), and combined used engine oil and plastic bag waste-modified bitumen (UEOPmB). To this end, all binders were prepared and stored at 163 °C for 48 h under continuous low agitation of 300 rpm. Stored and unstored binders were characterized using physical and rheological tests. Rheological derived indicators such as G*/sin δ, Shenoy's rutting parameter, G* sin δ, Low Shear Viscosity (LSV), and predicted Zero Shear Viscosity (ZSV) based on Cross and Carreau models were used to predict rutting and fatigue resistance of the binders. Results show that high-temperature storage provokes physical hardening of the binders. The results demonstrate that both pure and modified binders remain however thermally stable during storage. WPmB and UEOPmB exhibited higher critical rutting temperatures (> 75 °C) than PB and UEOmB (about 71 °C). Moreover, the inclusion of UEO influences positively fatigue resistance of the binders. It has been found that both critical rutting and fatigue temperatures of the tested binders remained unaffected by high-temperature storage. [ABSTRACT FROM AUTHOR]
