  • Reinforcing mat for reinforcing asphalt
    Patent number: 6168118
    Abstract: The invention relates to a reinforcing mat (1) for reinforcing a top layer of a ground, which top layer consists of bitumen, asphalt or a hydrocarbon-containing material of like nature, in which the reinforcing mat (1) is a mat woven with longitudinal wires (2, 3) and provided with reinforcement elements (4) running in the transverse direction of the mat, in which the reinforcement elements (4) consist of helically twisted steel profiled wires of essentially rectangular cross section.
    Type: Grant
    Filed: July 26, 1999
    Date of Patent: January 2, 2001
    Assignee: N.V. Bekaert S.A.
    Inventors: Yves Vancraeynest, Johan Veys
  • Preparation of bituminous concrete comprising wire pieces
    Patent number: 6159278
    Abstract: The invention relates to the manufacturing of a castable hot mixture of bituminous concrete, in which a multiplicity of steel wire pieces are equally distributed in the mixture. According to the invention, an ingredient is used in the form of a multiplicity of bundles in which the wire pieces are held together by a binding substance that is able to disintegrate in cementitious concrete, as already known, but that in addition is disintegrated by melting, in such a way that such bundles are usable for both cementitious and bituminous concretes.

  • Steel fiber reinforced concrete with high flexural strength
    Patent number: 5865000
    Abstract: Steel fiber reinforced concrete with very high flexural strength. A concrete composition is used with a compressive strength P of at least 80 N/mm.sup.2. Mixed in the concrete are fibers made by a cold work hardening cross-section reduction operation, having a length-to-thickness ratio ranging from 60 to 120, and with a grappling form. The tensile strength T of the steel is in a proportion with respect to the compressive strength P according to the formula T/P>17.
