DESIGN AND CONSTRUCTION OF HORIZONTAL DRAINS USING LARGE-SIZED SHREDDED SCRAP TIRES

The objectives of the research are to verify the feasibility of large sized shredded scrap tires for use as a horizontal subsurface drain and to develop a rational design procedure for such drains. The scope of the study includes laboratory tests to characterize the compressibility and hydraulic conductivity of the shredded tires, field testing of a prototype drain, and development of design guidelines. The results of the research demonstrate that a horizontal drain constructed with large sized shredded scrap tires provides effective drainage and lowering of the water table in low permeability soils.
