    摘要： This invention relates to bituminous compositions and methods of producing the same. More particularly, the invention relates to the production of bituminous compositions formulated with performance-graded bitumen-containing solvent-free bitumen emulsions which exhibit controllable, temperature-dependent interfacial rheology. When employed in paving applications, these bituminous compositions develop adhesive strength and load-bearing strength properties at rates comparable to traditional hot mix paving compositions and at rates faster than traditional cold mix paving compositions.

    摘要： The present invention relates to a bituminous composition for load-bearing paving applications. The 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:
    (j) hard bitumen in an amount from 50% to 75% by total weight of the bitumen emulsion, the hard bitumen having a penetration number of no more than 220 dmm at 25°C as determined according to ASTM standard method D5, and
    (ii) an emulsifier in an amount from 0.05% to 2% by total weight of the bitumen emulsion; and

    (b) an aggregate in an amount from 90% to 98% by total weight of the bituminous composition,

    wherein the hard bitumen coats a surface of the aggregate in the bituminous composition, and the bituminous composition is characterized by a temperature of from 50°C to 140°C prior to load-bearing paving applications.
