  • Publication number: 20210155557
    Abstract: An asphalt-cement concrete (“ACC”) interlayer formed of a plant-mix material reinforced with aramid fibers, deposited at a thickness of at least one inch (1?) over a Portland-cement concrete (“PCC”) or ACC base, can extend the service life of a hot-mix asphalt (“HMA”) surface layer installed over the interlayer by retarding or preventing “reflected” cracks—cracks in the surface layer that correspond to cracks, damage and irregularities in the PCC or ACC base. When the surface layer's useable life has expired, it can be removed and replaced, and the interlayer can continue to protect the new surface layer.

  • Patent number: 10766817
    Abstract: Embodiments of the invention enhance the performance of concrete mixtures, and have the flexibility to be used in both a variety of traditional poured concretes, as well as in sprayed concrete applications and geotechnical solutions which is commonly considered a cement application. It is an aspect of the present invention to provide a cementitious material comprising fly ash, wollastonite and nepheline syenite which is flexible enough in nature and chemistry to be used in a variety of concrete application which are poured and sprayed, as well as in blended into and within traditional cement applications. The use of a graduated blend of mineral fibers and industrial minerals also provide marked benefits to reduce both project cost and environmental impact.

  • 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.

  • Publication number: 20170291852
    Abstract: Reinforcing filaments or fibers, such as aromatic polyamide (aramid) fibers, can be reliably measured and consistently mixed into asphalt cement concrete by soaking the fibers in a wetting agent, then severing them to a desired length, and mixing the segments with other ACC ingredients. The wetting agent holds the fibers together loosely, so they can be distributed more uniformly throughout the ACC without clumping. The wetting agent soaks into the ACC mixture and/or evaporates, leaving the reinforcing fibers behind.
