The effects of ageing on the microstructure and dynamic rheological properties of three modified asphalt binders are investigated. The asphalt modifiers used comprise crumb rubber (CR), styrenebutadienestyrene (SBS) block copolymer and a blend or combination of CR and SBS (CCR). To investigate the...
This paper is a review of research that has been conducted on polymer modified binders over the last three decades. Polymer modification of asphalt binders has increasingly become the norm in designing optimally performing pavements, particularly in the United States, Canada, Europe and Australia. Spe...
The introduction of modified asphalt binders provided transportation agencies an effective tool to design balanced mixtures that can resist conflicting distresses while maintaining good long-term durability. While conventional polymer modified asphalt mixtures have shown improved long-term performance, it is ...

The physico-chemo-rheological properties of asphalt binder are critical for the long-term performance of asphalt pavement infrastructures. The objectives of this study are to characterize the physico-rheological properties of unmodified neat and polymer-modified asphalt binders with newly developed rheologica...

Rheological experiments revealed that the performance of high polymer-modified asphalt binders improved with increasing polymer content, with both high- and low- temperature performance benefiting from the combined effects of the butadiene and styrene segments in the polymer. The characteristic functional ...

Modified binders - obtained by adding thermoplastic macromolecular systems of plastomers or elastomers to traditional pure asphalt cements for road construction - have existed for more than 20 years. These products are still poorly understood scientifically. Significant research must be undertaken to better...
