  • Patent number: 7662226
    Abstract: A process of producing an asphalt concrete with enhanced performance is provided by utilizing a primer comprising uintahite and an augmenter. The primer is added to a hot aggregate with a surface temperature of at least 250 deg. F. prior to addition of an asphalt-derived base binder. The primer forms a primer interlayer between the hot aggregate and the base binder. As a result, the asphalt concrete has enhanced performance when compared with other asphalt concretes produced without a primer being added.

  • Patent number: 5728202
    Abstract: Tar sand and Gilsonite are preferably crushed together so that the Gilsonite overcomes the stickiness of the tar sand and the tar sand alleviates Gilsonite dust, the relative proportions and the character of Gilsonite being such as to produce an additive product for an asphalt, usually refinery asphalt, and a resulting modified asphaltic cement for paving purposes to simulate Trinidad Lake Asphalt. One embodiment of the additive composition of the invention results in an asphaltic cement that outperforms that produced by use of Trinidad Lake Asphalt as the additive, while a second embodiment of the additive composition of the invention contains additional tar-sand-extracted bitumen and the resulting asphaltic cement more closely matches the performance of that containing Trinidad Lake Asphalt as the additive. The invention includes a system for extracting bitumen from tar sand and in one form provides for adding Gilsonite to the extracted liquid bitumen so it will effectively solidify when cooled.

  • Patent number: 5378272
    Abstract: A composition useful in copying and printing is described. In one embodiment, the composition comprises a purified fraction of uintaite and a thermoplastic polymer. Preferably, the composition comprises a maltene-enriched fraction of uintaite derived by solvent extraction, a thermoplastic polymer and a colorant. In another embodiment, the present invention is an electrophotographic method comprising the steps of generating a latent electrostatic image; developing said latent image with a toner comprising a purified fraction of uintaite; and fixing said toner. The present invention is also a printing ink emulsion comprising a maltene-enriched fraction of uintaite.

  • Patent number: 4231884
    Abstract: A water retardant composition comprising a mixture of a low density granular mineral material coated with a water repellant material, and a finally divided limestone or other carbonate or silicate mineral particles also coated with a water repellant material. The low density granular mineral material is preferably selected from the group consisting of expanded perlite, expanded vermiculite, expanded shale and pumice rock. The carbonate or silicate mineral particles are preferably selected from the group consisting of talc, clay, sericite, unexpanded perlite, magnesium silicate and aluminum silicate. Preferably, the low density granular mineral material is coated with a silicone or asphalt, while the limestone or other carbonate or silicate mineral material is preferably coated with a silicone or a salt of stearic acid.

  • Patent number: RE35163
    Abstract: A water-based drilling mud additive comprising a preblended combination of about 2 parts of high softening point uintaite, about 1 part of a lower softening point uintaite, about 1 part of causticized lignite, and a strongly lipophilic, non-ionic surfactant is disclosed. This composition decreases shale sloughing and bore-hole instability during drilling of wells.
