There is provided a method for making bituminous compositions comprising water-in-oil bituminous dispersion and aggregate by the steps of: preparing a solvent-free, water-in-oil bituminous dispersion comprising: (1) bitumen, in an amount from about 75.0% to about 95.0% by total weight of the bitumen dispersion; (2) a surfactant in an amount from about 0.05% to about 2.0% by total weight of the bitumen dispersion; and (3) water in an amount to complete the water-in-oil bituminous dispersion, and producing the bituminous composition having a temperature from about 50° C. to about 120° C. by mixing: (1) the water-in-oil bituminous dispersion of step (A), having a temperature from about 75° C. to about 95° C., in an amount from about 2.0% to about 10.0% by total weight of the bituminous composition, and (2) aggregate, having a temperature from about 60° C. to about 140° C., in an amount from about 90.0% to about 98.0% by total weight of the bituminous composition.
