Patent ID: 7833338

Claim:
Bituminous composition comprising: (a) solvent-free, oil-in-water bitumen emulsion in an amount from about 2% to about 10% by total weight of the bituminous composition, wherein the oil-in-water bitumen emulsion comprises: (i) bitumen in an amount from about 50% to about 75% by total weight of the bitumen emulsion, (ii) emulsifier package having an interfacial tension between the bitumen and water of less than 40 dynes/cm at a temperature of 26° C. and at an aqueous concentration of less than 0.1% weight, in an amount from about 0.05% to about 2% by total weight of the bitumen emulsion, (ii) water in an amount to complete the emulsion; and (b) aggregate in an amount from about 90% to about 98% by total weight of the bituminous composition; and wherein the bituminous composition is in an absence of bitumen having a penetration number of more than 220 dmm as determined according to an ASTM standard method D5 at 25° C., and wherein the bituminous composition has a temperature ranging from 50° C. to 140° C.
