Patent ID: 8444760

Claim:
Bituminous composition comprising: (a) a bitumen emulsion in an amount from 2% to 10% by total weight of the bituminous composition, wherein the bitumen emulsion comprises: (i) hard bitumen in an amount from 50% to 75% by total weight of the bitumen emulsion, the hard bitumen being characterized by a penetration number of 100 dmm or less at 25° C. as determined according to the American Association of State Highway and Transportation Officials (AASHTO) Method T49, and (ii) emulsifier in an amount from 0.05% to 2% by total weight of the bitumen emulsion, the emulsifier having a Hildebrand solubility parameter of at least 19 (MPa)½; and (b) aggregate in an amount from 90% to 98% by total weight of the bituminous composition, wherein the bituminous composition is at a temperature range of 50° C. to 140° C., the hard bitumen wets a surface of the aggregate, and the emulsifier enhances the bitumen wetting of the aggregate surface.
