Abstract
This invention relates to a bitumen-based composition comprising a ternary mixture of (a) 52-78 wt % bitumen, (b) 20-40 wt % polyolefin and (c) 2-8 wt % of a butadiene-styrene copolymer. Said composition is useful alone for sealing purposes as a melt or a solution, and is also useful for the production of composite sealing sheets.
