Polymer Modified Hot Mix Asphalt — Oregon Experience

Source

The Oregon Department of Transportation (ODOT) has undertaken research into polymer modified asphalt binders in hot mix asphalt (HMA) with the expectation that such binders have the potential to provide more cost-effective, long-lasting asphalt concrete pavement. The research has involved three field installations with control sections of conventional asphalt and a laboratory study. Modifiers used in field installations were ethylene-vinyl-acetate (EVA), styrene-butadiene (SB), and styrene-butadiene-rubber (SBR). This paper discusses ODOT's research efforts with polymer modified HMA, and summarizes the findings of this research. ODOT's adoption of the Pacific Coast Conference on Asphalt Specifications' “Performance Based Asphalt Cement Specifications” is the next logical step based on knowledge gained from these research efforts.
