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. 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.

Abstract translation: 本发明涉及用于各种应用的增强纤维的混合物。 特别地，增强纤维的混合物可用于水泥组合物，例如波特兰水泥混凝土和沥青水泥混凝土组合物，以减少或排除在放置时在水泥混凝土中形成的空隙和/或裂缝。 增强纤维的混合物包括多个第一纤维和多个不同的第二纤维。 第一和第二纤维可以根据粗糙度/细度，熔融温度，旦数和具体化学或材料组成而不同。 在某些实施方案中，多个第一纤维和多个不同的第二纤维中的一个具有低于沥青水泥混凝土组合物的温度的熔融温度，使得多个第一或不同的第二纤维用作载体/缓冲剂 改善波特兰或沥青水泥混凝土组合物中纤维的分布和分散。
