excessive production and stockpile of scrap tires cause some environmental and sanitary risks throughout the world. to manage these materials, possible use of soil-tire mixtures has been recently propounded in civil engineering projects. a few studies previously have been conducted to evaluate behavior of clay-tire mixtures, while swelling properties, consolidation and settlement characteristic...

recently, mixtures of clay-tire chips are used as construction material in civil engineering projects. with respect to the tending for using these materials, it is necessary to know their mechanical behavior. thereby, a number of undrained monotonic triaxial tests are carried out on the specimens of pure clay and clay-tire chip mixtures. mixed specimens prepared by mixing pure clay with 10%, 20...

This paper evaluates the feasibility of using shredded tires for removal of organic compounds from landfill leachate. From the batch sorption isotherm experiments, tire chips were found to have 1.4% to 5.6% of the sorption capacity of granular activated carbon on a volume basis. The sorption equilibrium occurred within 2 days for 0.6-, 1.3-, and 2.5-cm size tire chips. The capacity of tire chip...

waste tires, rubbers, plastic and steel materials, normally produced in every society, enter the environment and cause serious problems. these problems may, to some extent, be reduced by finding applications for them in engineering, for example, they can be used for geotechnical applications as backfill material and solving problems with low shear strength soils. such materials may be subjected...

One concern for recycle and reuse of scrap tires is the leaching of tire constituents (organic and inorganic) with time, and their subsequent potential harmful impacts in environment. The main objective of this study was to examine the leaching of dissolved organic carbon (DOC), dissolved nitrogen (DN), and selected inorganic constituents from scrap tires. Different sizes of tire chips and crum...

Materials such as waste tire chips were widely used to improve the strength of soil. The objective of this study is to discuss the residual strength or steady-state behavior of sand-waste tire chip mixtures. A series of undrained monotonic triaxial compression tests were conducted on reconstituted saturated specimens of sand and sand-tire chip mixtures with variation in the tire-chip contents f...

high volume of waste tires, problems associated with their disposal, aesthetic problems, and the expansion and innovation of reuse of used tire products is being addressed aggressively. Chipped or shredded tires are being used for a wide variety of products, including playground covers, doormats, roadbed, fill, shoes, and aggregate substitute in septic system drainfields. This Analysis of Tire ...

The 20-40mm particle size of crushed aggregate and rubber aggregate showed 100% passing but river sand showed zero%. The 10 mm particle size of river sand showed 100% passing. Hydraulic conductivity ranges from 0.5 cm/sec (0.2 inches/sec) for compressed 10–38 mm (0.4–1.5 inches) shreds to more than 20 cm/sec (8 inches/sec) for 25–64 mm (1– 2.5 inches) loose shred. Thermal conductivity varies fr...
