FLOW RESISTANT ASPHALT PAVING BINDER

摘要

Paving binders, especially hot mix paving structures, may be modified to have both storage stability and increased creep resistance by the addition of copolymers of ethylene with vinyl acetate or lower alkyl esters of acrylic acid and mathacrylic acid to the asphalt used in said binder, provided the asphalt has an asphaltene content of about 7 wt. % or less.
