摘要：
Bitumen/polymer compositions are provided containing a bitumen or a mixture of bitumens and, reckoned by weight of bitumen, 0.3% to 20% of at least one primary polymer selected among certain elastomers and plastomers and 0.01% to 12% of at least one olefinic polymer bearing epoxy or COOH groupings. The compositions are useful, directly or after dilution, to form bitumen/polymer binders for carrying out road surfacing, for coated materials or waterproof coatings.
