Us Patents

  • Rubber Modified Asphalt Cement Compositions And Methods

    view source
  • US Patent:
    7074846, Jul 11, 2006
  • Filed:
    Dec 12, 2003
  • Appl. No.:
    10/735276
  • Inventors:
    Laurence M. Sylvester - Tiburon CA, US
    Jimmy Lee Stevens - Riverside CA, US
  • Assignee:
    RAM Technologies, Inc. - Reno NV
  • International Classification:
    C08L 95/00
  • US Classification:
    524 71, 524 68
  • Abstract:
    The present invention discloses methods of making improved rubber modified asphalt cement compositions, and compositions made by the method, where the compositions are useful in paving, roofing, coating and other sealing applications. In one aspect, the method comprises combining asphalt, RVPR (or a blended mixture of asphalt and RVPR) and at least one dodecyl or tridecylbenzene sulfonic acid (SA), which can be linear (LAS) or branched (BAS), in the presence of moderate heat. After heating the resultant RMAC mixture exhibits at least one of the following: () an increase in softening point, () an increase in hardness, or () improved recovery from deformation. In another aspect, the invention teaches addition of at least one SA to previously manufactured RMAC to accomplish at least one of the following: () an increase in softening point, () an increase in hardness, or () improved recovery from deformation. For paving compositions, the resultant RMAC mixtures made by the methods of the invention are mixed with an appropriate grade of aggregate composition, and other paving materials as desired.
  • Quick-Setting Cationic Aqueous Emulsions Using Pre-Treated Rubber Modified Asphalt Cement

    view source
  • US Patent:
    7087665, Aug 8, 2006
  • Filed:
    Aug 29, 2003
  • Appl. No.:
    10/652725
  • Inventors:
    Laurence M. Sylvester - Tiburon CA, US
    Jimmy Lee Stevens - Riverside CA, US
  • Assignee:
    RAM Technologies, Inc. - Reno NV
  • International Classification:
    C08L 95/00
  • US Classification:
    524 61, 524 60
  • Abstract:
    Cationic aqueous emulsions of rubber modified asphalt cement (RMAC) useable for paving, seal coat, slurry seal, roofing, coating and other applications. First, a RMAC is prepared by combining 45 to 90% by weight asphalt with about 5% to about 55% by weight solid recycled rubber (e. g. , crumb rubber from used vehicle tires) under conditions that cause at least a substantial portion of the solid rubber to become liquified or otherwise incorporated into the asphalt. The RMAC may be treated with dodecyl benzenesulfonic acid (DDBSA) which causes reaction(s) to occur and results in a lowering of the viscosity of the RMAC. The RMAC (or DDBSA-treated RMAC) may then be emulsified in an aqueous medium to provide an aqueous emulsion.
  • Aqueous Asphalt Emulsions Containing Liquefied Or Devulcanized Recycled Rubber

  • US Patent:
    20030018106, Jan 23, 2003
  • Filed:
    Jun 5, 2002
  • Appl. No.:
    10/164350
  • Inventors:
    Laurence Sylvester - Tiburon CA, US
  • Assignee:
    RAM Technologies Group, Inc. - Reno NV
  • International Classification:
    C08K003/20
    C08K005/01
  • US Classification:
    524/060000, 524/062000
  • Abstract:
    Non thixotropic, aqueous emulsions prepared from rubber modified asphalt cement (RMAC). The RMAC is prepared by a method whereby recycled tire rubber is liquified or otherwise consumed by or incorporated into asphalt such that no more than 2% by weight of solid particulate rubber remains. The RMAC may be emulsified in an aqueous or partially aqueous emulsification solution using a one-step or multi-step emulsification process. These aqueous RMAC emulsions are useable in many applications including paving, seal coat, roofing and slurry seal applications.

  • US Classification:
    524 71
  • Abstract:
    Rubber modified asphalts and their methods of manufacture. One or more sulfonic acids is/are added to a mixture of asphalt and rubber particles, or to an existing rubber modified asphalt composition. Heat and/or mixing may be applied during or after addition of the sulfonic acid(s).
  • Asphalt Binder Compositions And Methods Of Use

  • US Patent:
    20110274487, Nov 10, 2011
  • Filed:
    May 6, 2011
  • Appl. No.:
    13/102393
  • Inventors:
    Laurence M. Sylvester - Tiburon CA, US
  • Assignee:
    RAM TECHNOLOGIES, INC. - Tiburon CA
  • International Classification:
    E01C 11/24

  • US Classification:
    404 72, 524 59, 1062731, 427140
  • Abstract:
    Asphalt binder compositions are formed by combining asphalt with a reclaimed or re-refined oil. The boiling point of the oil may be greater than its flash point. The asphalt may be polymer modified or non-polymer modified. These asphalt binder compositions may be combined with aggregate and/or other matter (e.g., rubber particles) to form cold patch compositions suitable for various applications such as patching potholes, cracks or other defects in roads, driveways, roofs or other paved surfaces.
