  • Compositions and methods for the introduction of reinforcement fibers in portland and asphalt cement concrete
    Patent number: 10882789
    Abstract: The present invention relates to a blend of reinforcement fibers for use in a variety of applications. In particular, the blend of reinforcement fibers can be used in cementitious compositions, such as Portland cement concrete and asphalt cement concrete compositions to reduce or preclude voids and/or cracks formed in the cement concrete upon placement. The blend of reinforcement fibers includes a plurality of first fibers and a plurality of different second fibers. The first and second fibers can be different based on coarseness/fineness, melting temperature, denier and specific chemical or material composition.
    Type: Grant
    Filed: July 23, 2019
    Date of Patent: January 5, 2021
    Assignee: FORTA, LLC
    Inventors: Jeffrey B. Lovett, Clifford Norman MacDonald, Tracy H. Lang
