    OverviewBackgroundRecycled pavement materialGradingPurposesBenefitsConcerns

    Crumb rubber is recycled rubber produced from automotive and truck scrap tires. During the recycling process, steel and tire cord (fluff) are removed, leaving tire rubber with a granular consistency. Continued processing with a granulator or cracker mill, possibly with the aid of cryogenics or by mechanical means, reduces the size of the particles further. The particles are sized and classified based on various criteria including color (black only or black and white). The granulate is sized by passing through a screen, the

  • Rubber Crumb an overview ScienceDirect Topics

    Crumb rubber may be used to replace a weight fraction of sand in the manufacturing of concrete products. Khatib and Bayomy (1999) studied the ability of concrete mixes where natural sand was replaced with crumb rubber at 5%–100%, by volume. Results showed that the ability decreased with increasing rubber sand content.
