  • 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

  • Patent number: 9926672
    Abstract: Reinforcing fibers, such as aromatic polyamide (“aramid”) fibers, are treated by coating with or embedding in a binder such as a Fischer-Tropsch wax. The treated fibers are divided into suitably-sized units, which are added to bitumen, aggregate and other ingredients in an asphalt cement concrete mix. The units shed fibers into the mix during the manufacturing process so that the fibers are distributed fairly evenly throughout the asphalt mixture. The binder may also impart beneficial qualities to the finished asphalt concrete.

  • Patent number: 4884596
    Abstract: A plumbing fixture includes a tubular waterway and an enclosing cover. There is a space between the cover and waterway. In the method of manufacturing such plumbing fixture, a foam material consisting of a base and a catalyst therefor is positioned within the space between the cover and the waterway, with the foam material growing in the space until the space is completely filled and the waterway is secured to the cover. The foam material not only is the securing agent for the waterway and cover, but provides temperature, noise and vibration isolation therebetween.
