    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 methacrylic acid to the asphalt used in said binder, provided the asphalt has an asphaltene content of about 7 wt. % or less.

    摘要: Ethylene, alpha-olefin, non-conjugated bicyclic diene elastomeric polymers and/or polymer blends when compounded and formed into a calendered sheet, show surprising improvements for the combination in both green strength and peel adhesion in the unvulcanized state. Such green strength and peel adhesion provide benefits during calendering operations and subsequent joining of calendered sheets, while the compounded elastomeric polymers are in their green or unvulcanized state.
