Binders modified with plastomeric polymer have increased stiffness and are may be used in HSSs. R for crumb rubber materials. Crumb rubber is generally obtained from shredding and grinding of scrap rubber from vehicle tyres. When blended with bitumen the rubber behaves as a form of elastomer and is used in HSSs, SAMs and SAMIs. More information on various types of PMBs is provided in the Guide ...

01/01/2007 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. Specific polymers that have been used include rubber, SBR, SBS and Elvaloy ®.

The SBR modified binder shows an improvement in properties over unmodified asphalt. With the incorporation of the Pressure Aging Vessel, estimates of the long-term aging properties can be made. SBR Latex Polymers show dramatically lower long-term aging, which emphasizes the durability of the binder. The reduction in aging effects greatly increases the life of the pavement and, ultimately ...

While contractors should typically add B2Last to their asphalt binder upstream, Blankenship said they can also add it at a local hot mix plant binder tank, where permitted to do so by existing DOT and other regulators. No significant retrofitting is required to add B2Last to a mix at an asphalt plant. The only possible addition would be an injection port, but, in many cases, those are already ...
