TLDR
In this paper, the Multi-Stress Creep and Recovery (MSCR) test was used to validate the compliance of binder compliance to mixture rutting for modified and neat binders.Abstract:
The Multi-stress Creep and Recovery (MSCR) Test is currently being considered as a replacement for the Superpave high temperature binder criteria G* sinδ. The MSCR test can distinguish between the rutting properties of both neat binders and polymer modified binders. The test is run on the same dynamic shear rheometer test equipment currently used for the current Superpave binder testing and is easy to run. The validation of the MSCR compliance value Jnr to rutting was done through extensive mix testing using laboratory rut testers, large Accelerated Loading Facilities and actual roadway sections. This paper covers the validation of the MSCR test binder compliance value Jnr to mixture rutting for modified and neat binders. Multiple binders and mix types are included in the validation and it is demonstrated that the MSCR test provides a much better correlation to mixture rutting than the existing Superpave binder criteria.read more

Evaluation of aging behaviors of asphalt binders through different rheological indices
TL;DR: In this paper, the effects of different rheological indices which present tighter and clearer correlation with asphalt mixture performance in evaluating asphalt binder aging behaviors, these indices including complex modulus (G∗) and phase angle (δ) master curves, rutting factor, zero shear viscosity (ZSV), non-recoverable compliance (Jnr), fatigue factor (G ∗·sinδ), and DSR function (DSRFn).
