Polymer Modification of Paving Asphalt Binders

1994-7-1  • Polymer modifiers for asphalt binders which contain a large percentage of butadiene (50% or greater), exhibit improved low temperature properties. This was observed as a decreased T g for a polybutadiene modified asphalt measured using dynamic mechanical analysis. Also direct tension results for SB (50% butadiene) -modified asphalt binders showed a marked increase in low temperature
