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:

Storage stability and rheological properties of asphalt modified with waste packaging polyethylene and organic montmorillonite
TL;DR: In this article, asphalt was modified using waste packaging polyethylene (WPE) and organic montmorillonite (OMt) and the storage stability and rheological properties of the resulting material were investigated.

Comparative analysis of the performance of asphalt concretes modified by dry way with polymeric waste
Pedro Lastra-González,Miguel A. Calzada-Pérez,Daniel Castro-Fresno,Ángel Vega-Zamanillo,Irune Indacoechea-Vega +4 more
TL;DR: In this paper, an asphalt concrete has been modified by adding four polymeric wastes: polyethylene (PE) from micronized containers, polypropylene (PP) from ground caps, polystyrene (PS) from hangers and rubber from end-of-life tyres (ELT).

Evaluation of Low-Temperature and Elastic Properties of Crumb Rubber- and SBS-Modified Bitumen and Mixtures
TL;DR: In this paper, the performances of bitumen and asphalt mixtures modified by crumb rubber (CR) were compared with those modified by styrene-butadiene-styrene (SBS).
Journal ArticleDOI
Performance evaluation of linear and nonlinear nanocomposite modified asphalts
TL;DR: In this paper, the effects of nanoclay on two grades of styrene-butadiene-styrene (SBS) modified asphalts, linear and branch, have been investigated.

Utilizing bio-char as a bio-modifier for asphalt cement: A sustainable application of bio-fuel by-product
TL;DR: In this article, the use of bio-char derived from switchgrass through different types of pyrolysis was tested as a bio-modifier for asphalt binder, and it was found that biochar was capable of reducing the temperature susceptibility and significantly increasing the rutting resistance of the asphalt.

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.
