  • Patent number: 9074328
    Abstract: A method for repairing an aged or damaged asphalt pavement is provided. The method involves preparing a surface of the aged or damaged asphalt pavement by filling in deviations from a uniform surface plane with dry aggregate and compacting the dry aggregate; applying a reactive asphalt emulsion to the prepared surface; and passing an emitter over the prepared pavement, wherein the emitter generates electromagnetic radiation having a wavelength of from about 2 microns to 1 mm that penetrates into the pavement to a depth of at least 2 inches. The asphalt pavement is repaired by disturbing voids and interstices in the damaged pavement without dehydrogenation of the asphalt, such that oligomers present in the aged asphalt are linked together into longer polymer chains to improve ductility of the aged asphalt.

  • Publication number: 20150147465
    Abstract: Provided herein is a tack coat for use with paving applications and a method of making the same. The tack coat is substantially non-tracking, and includes asphalt, a pH adjustor, an emulsifier, acrylic, and water. In certain embodiments, the tack coat may also include a stabilizer to prevent settling of the emulsion during storage. The method of producing the tack coat involves heating the asphalt in one tank, and heating the water and emulsifier in a second, separate tank. This mixture of the water and emulsifier is referred to as soap, and is then mixed with asphalt, and the acrylic may be added to the mixture immediately thereafter, with a stabilizer, or later, just prior to shipment of the product, in which case a stabilizer may not be required. The tack coat exhibits moderate softness, with a penetration value above 40 dmm.

  • 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: 7951857
    Abstract: The present invention relates to bituminous compositions suitable for use in paving applications containing water-in-oil bitumen dispersion of paving grade bitumen such as penetration-graded, viscosity-graded and/or penetration-graded varieties that is substantially free of volatile solvents and made by controlling temperature-dependent interfacial rheology through the use of selected surfactants. The invention paving compositions are suitable for use in the construction of load-bearing, high-traffic pavements at a temperature range lower than that required for conventional hot-mix bituminous paving compositions, yet with similar or superior compaction to densities property and at least equal cure rate.

  • Patent number: 7927413
    Abstract: A foamed asphalt cement nozzle assembly is adapted for use in connection with a mixer for mixing aggregate materials and asphalt cement to make asphalt concrete. The foamed asphalt cement nozzle assembly includes a foamed cement mixing chamber, a first inlet for liquid asphalt cement and a second inlet for water, each of which is in fluid communication with the foamed cement mixing chamber. An outlet for foamed asphalt cement is also provided, which outlet is in fluid communication with both the foamed cement mixing chamber and the mixer. The invention also comprises a method for making asphalt concrete using foamed asphalt cement. The method includes introducing aggregate materials into the mixer and heating the aggregate materials to a temperature at least as high as the boiling point of water but no higher than about 285° F.
