COMPOSITIONS AND METHODS FOR THE INTRODUCTION OF REINFORCEMENT FIBERS IN PORTLAND AND ASPHALT CEMENT CONCRETE
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. In certain embodiments, one of the plurality of first fibers and the plurality of different second fibers has a melting temperature that is lower than the temperature of an asphalt cement concrete composition such that the plurality of first or different second fibers serves as a carrier/buffer to improve distribution and dispersion of the fibers in the Portland or asphalt cement concrete composition.
