| abstract |
These bitumen / polymer compositions contain a bitumen or mixture of bitumens and, counted by weight of the bitumen, 0.3% to 20% of at least one primary polymer chosen from certain elastomers and plastomers and 0.01% to 12% of at least one olefinic polymer bearing epoxy or COOH groups. Said compositions can be used, directly or after dilution, to form bitumen / polymer binders for producing road surface coatings, asphalt mixes or waterproofing coatings. |
