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:

Effect of Different Types of “Dry Way” Additions in Porous Asphalt Mixtures
Pedro Lastra-González,Jorge Rodriguez-Hernandez,Carlos Real-Gutiérrez,Daniel Castro-Fresno,Ángel Vega-Zamanillo +4 more
TL;DR: In this paper , the use of the most conventional types of polymers (two types of SBS, one type of BS, and rubber from end-of-life tires), dry added, as an alternative method.
Elimination of Empirical, Ineffective and Expensive PG Plus Tests to Characterize Modified Binders
TL;DR: In this paper, the main goal of this research is to investigate alternative test methods that can be conducted using a Dynamic Shear Rheometer (DSR) and to determine their effectiveness.

Rheological analyses of binders modified with triple combinations of Crumb-Rubber, Sasobit and Styrene-Butadiene-Styrene
Manuel Lagos-Varas,D. Movilla-Quesada,A.C. Raposeiras,P. Monsalve-Cárcamo,Daniel Castro-Fresno +4 more
TL;DR: In this article , a triple modification of Crumb-Rubber (CR) and Styrene-Butadiene-Styrene Copolymer (SBS) with Sasobit wax has been proposed.

Rutting on asphalt binders and mixtures modified with PPA and Elvaloy®: laboratory aspects and rheological modeling
TL;DR: In this paper , a study aimed at evaluating the rutting resistance of the AC+PPA at typical Brazilian high pavement temperatures was conducted. But the results showed that AC+Elvaloy and PPA did not show the same pattern of behavior because the flow number (FN) was only 17% higher than the one of the original binder.

Comparing the performance of SBS and thermoplastics modified asphalt binders and asphalt mixes
TL;DR: In this article , the conventional, rheological, morphological, and asphalt mix performance among SBS and several thermoplastics (TPs) modified binders was comprehensively compared.

Polymer modified asphalt
TL;DR: In this paper, the authors present an overview of the characteristics of polymerasphalt binders, mostly used in the paving industry, focusing on the relationships of composition and formulation with the properties of the binder, and the relationship of binder properties and performance of the mixture.

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.
Journal ArticleDOI
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.
