Influence of Six Rejuvenators on the Performance Properties of Reclaimed Asphalt Pavement (RAP) Binder and 100% Recycled Asphalt Mixtures
TL;DR: In this paper, 100% recycled hot mix asphalt lab samples were modified with five generic and one proprietary rejuvenators at 12% dose and tested for binder and mixture properties, which ensured excellent rutting resistance while providing longer fatigue life compared to virgin mixtures and most lowered critical cracking temperature.

Rheological Behaviour of WMA-Modified Asphalt Binders with Crumb Rubber
Emilio Turbay,Gilberto Martinez-Arguelles,Tatiana Navarro-Donado,Edgar H. Sanchez-Cotte,Rodrigo Polo-Mendoza,Elvis Covilla-Valera +5 more
TL;DR: In this paper , the mechanical and rheological properties of a 60/70 penetration grade asphalt binder modified with Crumb Rubber (CR) and WMA chemical additives (Evotherm M1 and Iterlow T) were investigated.

Rejuvenation of aged asphalt binders by waste engine oil and SBS blend: Physical, chemical, and rheological properties of binders and mechanical evaluations of mixtures
TL;DR: In this paper , a study was carried out to evaluate the simultaneous effects of 70% waste engine oil (WEO) and 30% SBS copolymer as a compound rejuvenator (WS-rejuvenator) on the performance of asphalt binders and mixtures containing RAP binders.
Journal ArticleDOI
Effect of aging and rejuvenation on adhesion properties of modified asphalt binder based on AFM.
TL;DR: In this article, the micromorphology and surface adhesion of modified asphalt binder in microstructure during aging and rejuvenation were measured by atomic force microscopy, and the average roughness value was used as the index to evaluate the micro-morphology of asphalt binders.
