  • Patent number: 8088210
    Abstract: A bituminous composition including, based on total weight of the bituminous composition, (a) hard bitumen in an amount of 0.5% to 7.5% by weight, the hard bitumen being characterized by a penetration number of 100 dmm or less at 25° C. as determined according to the American Association of State Highway and Transportation Officials (AASHTO) Method T49; (b) emulsifier in an amount of 0.0005% to 0.2% by weight, wherein the emulsifier has a Hildebrand solubility parameter of at least 19 (MPa)1/2; (c) water; and (d) aggregate in an amount of 90% to 99% by weight, the aggregate having an aggregate surface that is wetted with the hard bitumen, wherein the bituminous composition is at a temperature ranging from 50° C. to 140° C.

  • Patent number: 7972429
    Abstract: 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.

  • Patent number: 6669763
    Abstract: A composition for application to a surface and a method of making the same, said composition comprising at least one wax; at least one reaction product derived from a first surfactant and a second surfactant; and between 40% and 99.8% water by weight. The composition is made by: a) forming an emulsion by combining the water and the wax after heating both the water and the wax to a temperature greater than the melting point of the wax, where at least one of said water and said wax contains said first surfactant, said first surfactant being selected from the group consisting of a cationic surfactant and an anionic surfactant; and b) adding said second surfactant to the emulsion, said second surfactant having a charge which is opposite to that of said first surfactant.

  • Patent number: 6586003
    Abstract: New emulsion and micelle formulations are described as are complexes of these formulations with biologically active substances. The novel formulations are different from cationic lipid vectors such as cationic liposomes in that the complexes formed between biologically active substances and the emulsion and micellar formulations of this invention are physically stable and their transfection activity is resistant to the presence of serum. These novel formulations are disclosed to be useful in areas such as gene therapy or vaccine delivery.
