Patent number: 6852779Abstract: Compositions produced by forming a homogenous mass consisting of a bitumen matrix wherein a cross-linked and/or functionalized elastomer produced in situ from a precursor elastomer is dispersed in a uniform manner and makes up 0.5-30% of the weight of the bitumen matrix. The bitumen matrix is created by associating 95%-20 wt. % non oxidized bitumen having a penetrability of 20-900 and 5-80 wt. % oxidized bitumen having a penetrability of 10-90. The compositions can be used as bitumen binders in the production of coverings.Type: GrantFiled: June 21, 2000Date of Patent: February 8, 2005Assignee: ELF Antar FranceInventors: Jean-Pascal Planche, Patrick Turello, Pierre Chaverot, Patrice Vegny
