Abstract:
PCT No. PCT/FR95/00497 Sec. 371 Date Mar. 11, 1996 Sec. 102(e) Date Mar. 11, 1996 PCT Filed Apr. 14, 1995 PCT Pub. No. WO95/28446 PCT Pub. Date Oct. 26, 1995Bitumen/polymer compositions with a broadened plasticity range are produced by stirring together a bitumen or bitumen mixture and a sulphur-cross-linkable elastomer as well as a sulphur-donating coupling agent at 100 DEG -230 DEG C. to give a cross-lined bitumen/polymer composition, stirring an acid or acid anhydride inorganic admixture into the composition at 100 DEG -230 DEG C., and maintaining the resulting reaction medium at 100 DEG -230 DEG C. while stirring for at least 20 minutes. Such bitumen/polymer compositions may be used directly or in dilute form to provide bituminous binders for road surfaces, coated materials and sealing coatings.
