Research on self-healing behavior of asphalt modified by polyurea elastomer containing dynamic disulfide/diselenide bond
TL;DR: In this article , three kinds of polyurea elastomers (PE) with self-healing properties were prepared: the elastomer containing disulfide bonds (PE-S1), obtained by one-step copolymerization, and the ELastomers containing dynamic disulfides/diselenide bond (PE -S2/PE-Se) obtained by two-step co-polymerization.

Evaluation of the Relationship between Asphalt Binder Properties and Non-Load Related Cracking
TL;DR: In this article, a laboratory study was conducted to evaluate if there was any potential relationship between asphalt binder properties and non-load related cracking, as part of a research project involving airfield asphalt pavements.

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).

Effect of organo-montmorillonite on aging properties of asphalt
TL;DR: In this paper, the effects of organo-montmorillonite (OMMT) on thermo-oxidative and ultraviolet (UV) aging properties of asphalt were investigated, and the results showed that the viscosity aging index (VAI) and softening point increment (Δ S ) of OMMT modified asphalt decrease significantly due to introduction of OMMT and the ductility retention rate of the modified asphalt is also evidently higher than that of the pristine asphalt after thin-film oven test (TFOT) and pressure aging vessel (PAV) aging.
