Asphalt material

An asphalt product comprising:

• Z1) from 90 wt. % to 98 wt. % of mineral aggregate;
• and
• Z2) from 2 wt. % to 10 wt. % of a bitumen composition comprising
• T1) from 99 wt. % to 75 wt. % of bitumen, and
• T2) from 1 wt. % to 25 wt. % of a polymer composition comprising:
• A) 5-35% by weight of a propylene ethylene copolymer containing 15% by weight or less of a fraction soluble in xylene at 25° C. (XSA), the amount of the fraction XSA being referred to the weight of A);
• and from 0.5 wt. % to 7.0 wt. % of ethylene derived units;
• B) 20-50% by weight of an ethylene homopolymer having 5% by weight or less of a fraction soluble in xylene at 25° C. (XSB) referred to the weight of B);
• and
• C) 30-60% by weight of a terpolymer of ethylene, propylene and 1-butene derived units and containing from 45% to 65% by weight of ethylene units;
• and from 15% to 38% by weight of 1-butene units;
• and containing from 30% to 85% by weight of a fraction soluble in xylene at 25° C. (XSC), the amount of ethylene units, 1-butene units, and the fraction XSC being referred to the weight of C);
• the amounts of A), B) and C) being referred to the total weight of A)+B)+C), the sum of the amount of A)+B)+C) being 100 wt. %;
• the amounts, wt. %, of T1+T2 being 100 wt. %.
