Crumb Rubber & Crack SealantsCrumb rubber, also referred to as ground rubber, is a wire-free fine rubber particle made by size reduction from scrap tires. Crumb rubber is made by a combination or application of several size reduction technologies. These technologies may be divided into two major processing categories, mechanical grinding and cryogenic reduction. Crumb rubber modified asphalt has been known to improve the rheological properties at low and high temperatures and provide a pavement life up to three times longer than conventional asphalt. Western Technologies was a pioneer in the early research and development of crumb rubber modified asphalt and continues to be one of the leaders in this developing technology.

Sealing cracks in asphalt concrete pavements is a commonly used maintenance procedure that can reduce pavement deterioration by restricting surface water penetration into underlying base and subbase layers. This helps maintain pavement structural capacity and limits future pavement degradation. Western Technologies is one of only several independent laboratories in the United States capable of testing and evaluating crack sealants.
