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