• Abstract:
  This report presents a summary of a literature review to determine the most appropriate testing procedures for use with polymer modified asphalts. In examining testing procedures, it was necessary to study the effects of polymer modifiers on both binder and mix properties. The four additives most closely examined are styrene-butadiene (SB), styrene-butadiene-styrene (SBS), styrene-butadiene-rubber (SBR), and ethlene-vinyl-acetate (EVA). It was found that standard binder and mixture testing procedures may be successfully used with polymer modified asphalts. In addition of which are force ductility, toughness and tenacity, rubber industry tensile tests and dynamic shear analysis. A testing program is proposed which will result in recommendations for a specification for polymer modified binders in hot mix. A definite lack of study of long-term aging effects for polymer modified asphalt mixes was noted. Available information indicates a potential problem in this area and that additional research should be conducted.
