Abstract:
PCT No. PCT/FR97/00812 Sec. 371 Date Apr. 20, 1998 Sec. 102(e) Date Apr. 20, 1998 PCT Filed May 6, 1997 PCT Pub. No. WO97/43342 PCT Pub. Date Nov. 20, 1997Bitumen/polymer compositions are produced by contacting, between 100 DEG C. and 230 DEG C., under agitation, one bitumen or a mixture of bitumens with at least one olefinic polymer bearing epoxy or COOH groupings, then by incorporating in the product, an acid additive while the whole mixture is agitated at a range between 100 DEG C. and 230 DEG C. for at least 10 minutes. The product, which is subjected to treatment by the acid additive may still contain one or several additional polymers, for instance of the elastomer type cross-linkable with sulphur, and even be subjected to sulphur cross-linking before treatment. The bitumen/polymer compositions are useful directly or after dilution, to form binders for carrying out surfacing operations.
