Patent ID: 7993442

Claim:
A bituminous paving composition, comprising: (a) a high-concentration-emulsifier bitumen emulsion comprising: (a.1) bitumen characterized by a penetration number of less than 220 dmm as determined according to an ASTM standard method D5 at 25° C., in an amount from about 45% to about 98% by total weight of the emulsion, (a.2) an emulsifier additive in an amount from about 1% to about 20% weight based on the bitumen weight of (a.1), (a.3) water in an amount to complete the emulsion; (b) a non-emulsified bitumen having a penetration number of less than 220 dmm as determined according to an ASTM standard method D5 at 25° C.; (c) aggregate, wherein: (i) a combined weight of emulsified bitumen from the high-concentration-emulsifier bitumen emulsion of (a) and bitumen from the non-emulsified bitumen of (b) is in a range of about 1% to about 20% by total weight of the bituminous composition, and (ii) a weight of the aggregate is from about 80% to about 99% by total weight of the bituminous composition.
