摘要: A bituminous mixture having improved physical properties is obtained by adding to a bitumen a polyphosphoric acid (I) containing phosphorus, calculated as P.sub.2 O.sub.5, in amount from 80% to 87% by weight, and a polymer composition (II) comprising (A) a propylene homopolymer or copolymer, (B) optionally an ethylene copolymer fraction insoluble in xylene at ambient temperature and (C) a copolymer fraction soluble in xylene at ambient temperature.
