  • Publication number: 20200385611
    Abstract: An asphalt modifying binder product, which is essentially a cut-back bituminous binder, uniquely including a petroleum product, such as diesel fuel or alternatively an organic oil, including vegetable or animal derived fats or oils, or glycol, for use in the manufacture of cold-mix asphalt “CMA” and asphalt treated base products. When mixed with an dense-graded aggregate with fine aggregate fractions, a dense-graded and non-porous cold-mix asphaltic improved product is fomiulatede The improved product may be employed as a patching/paving material or an asphalt treated base, stays pliable for extended periods of time at an ambient temperature, and again meets the typical required specifications and standards, for stability, flow and voids, when tested as hot-mix asphalt or asphalt treated base.

  • Publication number: 20120252938
    Abstract: An asphalt modifying binder product, which is essentially a ‘cut-back’ bituminous binder, uniquely including a petroleum product, such as diesel fuel or alternatively an organic oil, including vegetable or animal derived fats or oils, or glycol, for use in the manufacture of cold mix asphalt “CMA” and asphalt treated base products. When mixed with an aggregate, the product blends within standard gradation ranges. The product may be employed as a patching/paving material or an asphalt treated base, either of which stays pliable for extended periods of time, and again meets the typical required specifications and standards, for stability, flow and voids, when tested as hot mix asphalt or asphalt treated base.
