Abstract:
A mixture made from or containing
T1) from 99 wt % to 75 wt % of bitumen, and
T2) from 1 wt % to 25 wt % of a polymer composition made from or containing
A) 5-35% by weight of a propylene homopolymer or a propylene ethylene copolymer;
B) 20-50% by weight of a copolymer of ethylene and a C3-C8 alpha-olefin containing from 1.0% to 20.0% by weight of alpha-olefin units; and
C) 30-60% by weight of a copolymer of ethylene and propylene containing from 25.0% to 75.0% by weight of ethylene derived units.
