A bituminous composition comprising a bitumen emulsion in an amount from about 2% to about 10% by total weight of the bituminous composition, and aggregate in an amount from about 90% to about 99% by total weight of the bituminous composition, wherein the bituminous composition is at a temperature range of about 50° C. to about 140° C. The bitumen emulsion comprises hard bitumen in an amount from about 50% to about 75% by total weight of the bitumen emulsion, the hard bitumen being characterized by a penetration number of about 100 dmm or less at 25° C. as determined according to the AASHTO Method T49, and an emulsifier in an amount from about 0.05% to about 2% by total weight of the bitumen emulsion, the emulsifier having a Hildebrand solubility parameter of at least of about 19 (MPa)½. Also disclosed are the methods of producing and using such bituminous compositions.
