“…This term was found to be inadequate in describing the rutting performance of bitumens. Developments led to the existence of Multiple Stress Creep and Recovery (MSCR) test [32]. MSCR test was run on RTFOT aged samples in accordance to ASTM D7405-08 using the dynamic shear rheometer [33].…”

Bitumen is adhesive that originates from crude oil and is temperature dependent material including hydrocarbon molecules. Paraffinic crude oils may provide bitumen of good quality or yield bitumen which is not suitable for pavement performance. Wax in bitumen has been referred to as petroleum wax and is obtained from refining of paraffinic crude oils. The effects of wax on bitumen properties depend on the following factors; the source, chemical composition and rheology of the bitumen as well as the content, type, composition and crystallization of the wax. Although high wax contents have been considered as a negative effect on the quality of the bitumen, there is no common agreement among the scientists regarding the effect on bitumen rheology and asphalt performance. The scope of this study is to evaluate the rheological properties of waxy bitumens obtained from different sources. Following the determination of wax contents by DSC (Differential Scanning Calorimetry) and EN 12606-1, waxy bitumens properties were evaluated using dynamic shear rheometer (DSR) and various conventional methods such as softening point, penetration, viscosity, and ductility. The high temperature performance levels of bitumen were also determined according to Superpave system by dynamic shear rheometer (DSR) test on samples before and after aging processes. Besides, bending beam rheometer (BBR) test has been conducted to investigate the lower critical temperatures of bitumens. Rutting performance of bitumens has also been evaluated using Zero Shear Viscosity (ZSV) and Multiple Stress Creep Recovery (MSCR) tests performed in creep mode.

“…More recently, D'Angelo [7] proposed multiple stress creep recovery (MSCR) test and the non-recoverable creep compliance J nr and the percent recovery were used to evaluate binder's high temperature properties. The MSCR test has been used to characterize the extent of dispersion of styrene-butadiene-styrene (SBS) in polymer-modified asphalts (PMA) and MSCR can be considered as an alternative to Elastic Recovery test, typically run by many highway agencies [8,9]. The validation of the MSCR compliance value J nr to rutting demonstrated that the MSCR test provides a better correlation to mixture rutting than the existing Superpave binder criteria [10].…”

“…Therefore, G*/sin δ cannot be taken for an effective evaluation index for high-temperature performance of asphalt binder. In recent years, Repeated Creep Recovery (RCR) test and Multiple Stress Creep Recovery (MSCR) test are considered to be more accurate methods (Delgadillo et al 2006;Masad et al 2009;Eric et al 2014). Unlike the controlled-strain mode by general rheological tests, RCR and MSCR tests both adopt controlled-stress mode, and perform a test cycle consisting 1s of loading and 9s of unloading to detect the recovery and residual shear strains of tested sample (Fig.1).…”

This study reviewed and compared the test methods for the high-temperature performance of asphalt binder, and selected repeated creep recovery (RCR) test to evaluate the high-temperature performance of three waste-based high-viscosity asphalt binders (WHABs, including D-I, D-II, and F) and a control sample (Tafpack-Super modified asphalt, TMA). Meanwhile, shear stress, test temperature, and aging degree of binders, which could influence high-temperature behavior of binders, were also investigated, and related evaluation indexes including recovery compliance (R), non-recoverable creep compliance (Jnr), and viscous stiffness modulus (Gv) were compared. Results show that WHABs has much better high-temperature performance than TMA; shear stress has the most prominent effect on binders’ high-temperature performance, followed by aging degree, and lastly the selected test temperature in γ–time curve results; R, Jnr, and Gv values results indicate aging degree has a significant effect on binders, and improving binders’ aging performance can greatly improve the high-temperature performance.
