Zusammenfassung: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.
