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:

Use of a MDI-functionalized reactive polymer for the manufacture of modified bitumen with enhanced properties for roofing applications
M.J. Martín-Alfonso,Pedro Partal,Francisco J. Navarro,Moisés García-Morales,Críspulo Gallegos +4 more
TL;DR: In this paper, the suitability of a reactive polymer, synthesized by reaction of 4,4′-diphenylmethane diisocyanate (MDI) with a low molecular weight polyethylene-glycol (PEG), as a modifying agent for the manufacture of bitumen-based waterproof membranes, was evaluated.
Journal ArticleDOI
Effect of ageing on the morphology and creep and recovery of polymer-modified bitumens
TL;DR: In this paper, an elastomer (radial styrene butadiene styrene, SBS) and a plastomer polymer (ethyl vinyl acetate, EVA) were mixed with one base bitumen at three polymer concentrations to investigate the changes in the morphology and rheological response of polymer modified bitumens used in road pavement construction caused by ageing.

Feng Zhang,Changbin Hu +1 more
TL;DR: In this paper, the physical properties of each modified asphalt were studied and compared, and LLDPE was confirmed as the right modifier in enhancing the high-temperature performance while dioctyl phthalate (DP) as a plasticizer was used further in improving low temperature properties.
Journal ArticleDOI
Low-temperature rheological and morphological characterization of SBS modified bitumen
TL;DR: In this paper, the effect of polymer modification on the dynamic rheological properties at low temperatures was investigated using the 4-mm DSR technique and fluorescence microscopy and temperature-modulated differential scanning calorimetry.
Journal ArticleDOI
Preparation and evaluation of waste PET derived polyurethane polymer modified bitumen through in situ polymerization reaction
TL;DR: In this paper, the authors demonstrate a new approach where in situ polymerization of monomers bis(2-hydroxyethyl) terephthalamide (BHETA) with diphenylmethane-diisocyanate (MDI) in the body of bitumen for the development of polyurethane based polymer modified bitumen, which is comparable performance under laboratory condition with conventional styrene butadiene styrene (SBS) based PMB.

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.
Journal ArticleDOI
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.
