Polymer modified asphalt binders
TLDR
A review of research that has been conducted on polymer modified binders over the last three decades can be found in this paper, where the elastic recovery test is good at determining the presence of polymers in an asphalt binder but is less successful at predicting field performance of the pavement.About:

Cement-less and asphalt-less concrete bounded by recycled plastic
TL;DR: In this article, the authors formulated Recycled Plastic Bounded Concrete (RPBC) with zero asphalt binder and zero Portland Cement (pCC) and analyzed the properties of the RPBCs with reference to PCC and ACs.

Life cycle assessment of asphalt variants in infrastructures: The case of lignin in Australian road pavements
TL;DR: In this paper, the authors presented the life cycle assessment (LCA) of lignin as a partial replacement for bitumen in Australian road pavements, which showed that a 5.72% reduction in Global Warming Potential (GWP) of CO2e Kg is possible through the substitution of 25% bitumen binder with Lignin.

Influence of modification process parameters on the properties of crumb rubber/EVA modified asphalt
TL;DR: In this article, the authors used Matlab software to fit out the formulae of ductility, penetration, and softening point difference of modified asphalt and shearing temperature, shearing time, and the shearing rate separately.

The performance of Agbabu natural bitumen modified with polyphosphoric acid through fundamental and Fourier transform infrared spectroscopic investigations
TL;DR: In this paper, the suitability of polyphosphoric acid (PPA) as a modifier in Agbabu natural bitumen (ANB) has been investigated with specific emphasis on Fourier transform infrared investigation and fundamental physical tests like penetration, softening point, fire and flash point and specific gravity.

Fracture resistance of HMA mixtures under mixed mode I/III loading at different subzero temperatures
Sadjad Pirmohammad,Abas Bayat +1 more
TL;DR: In this paper, fracture resistance of two types of hot mix asphalt (HMA) mixtures (i.e. the first one contained a normal binder, and the second one contained the same binder but modified by crumb rubber of recycled tyres) was successfully characterized using an asymmetric disc bend specimens.

Asphalt modified by styrene-butadiene-styrene triblock copolymer: Morphology and model
TL;DR: In this paper, the styrene-butadiene-styrene (SBS! triblock copolymer) was used to modify the asphalt binder and the morphology and engi- neering properties of the binders were investigated using transmission electron microscopy and dynamic shear rheometer.

Polymer-Modified Asphalt Cements Used in the Road Construction Industry: Basic Principles
TL;DR: In this paper, the basic principles of bitumen-polymer compatibility, the mechanism for modification, and the effect of the components on the properties of the modified binders are presented along with several specific problems related to the use of these products.
Classification of asphalt binders into simple and complex binders
TL;DR: The NCHRP 9-10 Project as mentioned in this paper evaluated the suitability of using the Superpave binder and mixture test system for modified asphalt binders, and the results indicated that modified binders will be used more in the future and that there are major concerns regarding the applicability of the superpave PG-grading system to modified asphalt binder.

Characteristics of polymers and polymer-modified binders
TL;DR: In this article, the properties of a number of polymers commonly proposed for polymer-modified bitumens (PMBs) were studied to suggest a way to select the polymer suitable for the required application; the prediction of the performance in the final application would allow bypass of the tests on PMBs and asphalt mixtures.
