Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
54 words
An asphaltic composition comprising a major amount of asphalt, a minor amount of a synthetic terpenic resin, and a minor amount of an interpolymer of ethylene, vinyl acetate, and an organic acid selected from the group consisting of acrylic, methacrylic, itaconic, maleic and fumaric acids; the alkyl hydrogen maleates and the alkyl hydrogen fumarates.
Claim 2
Dependent Claim
54 words
An asphaltic composition comprising a major amount of asphalt, a minor amount of a synthetic terpenic resin, and a minor amount of an interpolymer of ethylene, vinyl acetate, and an organic acid selected from the group consisting of acrylic, methacrylic, itaconic, maleic and fumaric acids; the alkyl hydrogen maleates and the alkyl hydrogen fumarates.
Claim 3
Dependent Claim
