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.

On the road again! An economic and environmental break-even and hotspot analysis of reclaimed asphalt pavement and rejuvenators
TL;DR: In this paper , the relative service life (SL) to break even economically and environmentally when using RAP and rejuvenators was determined, and the main contributors to the economic and environmental impact were identified.

Rheological properties of asphalt binder modified by nano-TiO2/ZnO and basalt fiber
TL;DR: In this article , different contents of nano-TiO2/ZnO and basalt fiber were used to prepare composite-modified asphalt binders, and the results indicated that incorporation of nanomaterials and fibers can significantly improve the high-temperature performance and fatigue life of composite-modifier asphalt binder before aging and after short-term, longterm, and ultraviolet (UV) aging.

Comparison by Fourier transform infrared (FTIR) spectroscopy of different ageing techniques: application to road bitumens
TL;DR: In this paper, the authors compared a direct and continued methodological approach of bitumen oxidation process (adapted IR cell), a road ageing, along with two ageing conventional tests: the Rolling Thin Film Oven Test (RTFOT) and the Pressure Ageing Vessel (PAV).
Interpretation of dynamic mechanical test data for paving grade asphalt cements
D W Christensen,D A Anderson +1 more
Abstract: Dynamic mechanical analysis, and other methods of rheological testing, have been used for many years on asphalt cement. Unfortunately, there currently exists some confusion over the interpretation of dynamic mechanical data on asphalt cements. In order to clarify appropriate methods of interpreting rheological data on paving grade asphalts, test data for a number of asphalt cements having widely different properties must be analyzed in light of rheological theory and appropriate mathematical models. The purpose of this paper is to describe various useful techniques for interpreting viscoelastic data on asphalt cements. Dynamic mechanical test data is emphasized, although many of the principles presented apply equally well to other types of rheological data.

A Review of the Fundamentals of Asphalt Oxidation: Chemical, Physicochemical, Physical Property, and Durability Relationships
TL;DR: In this paper, a summary of current physicochemical understanding of the chemistry, kinetics, and mechanisms of asphalt oxidation and its influence on asphalt durability is presented, focusing on how the component fractions of asphalt behave under oxidation, including the effects of the mineral aggregate and metals contained in asphalts.

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.
