The potential for use of shredded tire chips as a leachate drainage and collection medium: Design, construction and performance considerations
Old tires represent a potentially cost-effective construction material which can be used in the installation of leachate drainage and collection systems. Shredding of tires and using them in conjunction with granular soil materials enhances the long term performance of the leachate drainage and collection system. A typical design utilizing shredded tire chips involves the placement of a minimum one foot thick layer of tire chips on a granular soil layer overlaying the composite liner system. Protection of the liner from wire protruding from chips made form belted tires is essential. As the tire chips tend to clump together, placement and spreading must be in relatively thick lifts and performed by low ground pressure equipment. A fifty percent volume reduction in the tire chip layer can be anticipated as a result of normal loadings form the overlaying waste. Equivalent internal friction angles and cohesiveness for the tire chips should be estimated to ensure sufficient factors of safety against sideslope failure. The long term permeability characteristics of the tire chips (especially as a filter medium) and its resistance to clogging as a result of biological activity must be at least equal to that of typical granular soil materials traditionally utilized in leachate drainage and collection systems.
