  • Method for the production of cross-linked and/or functionalized bitumen/polymer compositions and use of said compositions in coverings
    Patent number: 6852779
    Abstract: 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.
