  • Patent number: 10471437
    Abstract: A method for producing a non-coalescing asphalt from raw natural asphalt herein referred to as TLA Cold Milled. Raw TLA is crushed into smaller particles and milled at ambient temperature. The milled TLA is passed through a first sieve to maintain the separation of the particles and to produce a damp milled TLA in a powdered state. The damp milled powdered TLA is dried by exposing it to heat and is thereafter cooled to ambient temperature. The dried and cooled powdered TLA is passed through the first sieve or another sieve to produce the TLA Cold Milled which may be packaged at ambient temperature in conventional bags. The milling of the asphalt results in each particle of inorganic matter within the asphalt being surrounded by bitumen and a thin film of inorganic material, producing asphalt in a non-coalescing form, i.e., the TLA Cold Milled.

  • Patent number: 10364535
    Abstract: A method of forming a pavement construction joint that involves dispensing a band of a void reducing joint composition on a substrate using at least one spray application vehicle, wherein the band comprises a width of about 4 to about 24 inches. A paving pass is applied over the band of joint composition, wherein the paving pass is positioned against an edge of a previously laid portion of pavement to form a pavement construction joint having a volume of air voids. At least a portion of the joint composition migrates upward to reduce the volume of air voids. The composition is resistant to flow when applied and migrates into hot mix asphalt in the area of the longitudinal joint to reduce air voids to 7% or less and reduce water permeability. The composition becomes tack-free quickly after application. The composition bonds to asphalt, concrete, brick, stone and metal.

    Abstract: Disclosed herein is a composition for solidifying soil and industrial waste. The solidifying composition contains 16-24 wt % of straight asphalt, 0.06-0.10 wt % of an emulsifier for asphalt, 0.8-1.2 wt % of light oil, heavy oil or a mixture thereof, 0.01-0.03 wt % of calcium chloride, 0.8-1.2 wt % of lignin, 0.7-1.3 wt % of an acrylic emulsion-based asphalt modifier, 0.13-0.21 wt % of sodium hydroxide, 0.22-0.34 wt % of oleic acid, and the balance of water. A solidified material formed using this solidifying composition has increased density, strength and elasticity, improved durability and a short curing time. Furthermore, the solidifying composition enables soil and industrial waste to be recycled as a substitute for stone materials, such that it allows material sources to be readily secured in public or construction work fields, leading to a reduction in construction cost, and can also contribute to the preservation of the natural environment.

    Abstract: A new ramming paste for aluminum reduction cell cathodes is a high swelling cold ramming paste made of a blend of pitch, light oil diluent and an aggregate comprising a mixture of anthracite and crushed anode butts or calcined coke. The presence of the crushed anode butts or calcined coke increases the sodium swelling index of the paste by about four times higher than that of regular ramming pastes. This new high swelling cold ramming paste may also contain an amount of a refractory hard material, such as TiB2.

  • Patent number: 6972047
    Abstract: It has been discovered that a synthetic flux oil can contain and deliver asphaltites, such as gilsonite, more easily and readily to an asphalt to improve its properties. The synthetic flux oil includes the asphaltite and a carrier oil. Depending on the nature of the carrier oil, the synthetic flux oil may or may not need to be heated during mixing and incorporation into the asphalt.

  • Patent number: 6712895
    Abstract: A method of producing a bituminous foam includes supplying a bitumen in water emulsion from a tank (2) into primary and secondary heating circuits (8, 34), whereby the emulsion is heated (via heating coils 12 and 12′) and its pressure raised such that, on discharge to ambient conditions via outlet pipes (30 or 30′), the emulsion foams as water evaporates therefrom.

  • Patent number: 6623554
    Abstract: A useful composition for protecting metal equipment from corrosion and/or other damage comprises 1) gilsonite, which is a mined asphalt; and/or some other natural-origin or naturally-derived resin, 2) a naturally-derived solvent such as d-limonene and/or other terpenes, and 3) a naturally-derived non-drying plasticizer such as fatty acid triglycerides. 4) Optionally, additives for controlling rheology, viscosity, lubricity, corrosion rates etc. can be added to obtain specific properties which may be desirable. The invention also relates to a method of preventing corrosion or other damage to metal equipment by applying the above-mentioned coating to the equipment by spraying, rolling and/or brushing.

  • Patent number: 6559206
    Abstract: The invention consists of a bitumen/resin composite emulsion for a road surface protection layer against the attacks of petroleum derivates, realised by mixing a first emulsion comprising at least one resin with a second emulsion comprising a bituminous binder and a resin crosslinking agent. A pigmentary preparation and/or a load made of a filler or sand or a fine sand or their combinations, can be incorporated to the first emulsion, the second emulsion or into the composite emulsion resulting from the mixture of both emulsions. The loaded composite emulsion enables the realisation of thin film-type surface coatings made of one or several layers.
