Abstract
The invention relates to improved bitumen compositions including: PA1 (A) 100 parts of bitumen PA1 (B) 0.1 to 10 parts of a copolymer of an alpha-olefin, of an unsaturated epoxide and of an ester of unsaturated carboxylic acid PA1 (C) 0.1 to 10 parts of a copolymer of an alpha-olefin and of an ester of unsaturated carboxylic acid, PA1 (D) 0 to 10 parts of a thermoplastic elastomer PA1 (E) 0 to 10 parts of a polymer which is reactive with (B) PA1 (F) 0 to 10 parts of an ethylene/vinyl acetate copolymer. These bitumens are stable when stored and resist rutting.
