Triaxial Determination of Shear Strength of Tire Chips
Publication: Journal of Geotechnical and Geoenvironmental Engineering
Volume 123, Issue 5
Abstract
Triaxial compression tests following stress paths of constant σ1 were conducted to determine the shear strength of five processed scrap tire products having different gradations and particle shapes. The interparticle frictional component was separated from the total shear strength according to the energy correction concept proposed by researchers. The experimental results show that all five tire chip products have ultimate internal friction angles of 45° to over 60°. The interparticle frictional component of the strength was fully mobilized and nearly reached a constant value after approximately 5% axial strain. The experimental results confirmed that the strength parameter obtained with constant σ1 was more reasonable. This finding is supported by field observation in which the tire chips have an angle of repose ranging from 37° to 43° (loosely stock piled) and up to 85° (compacted). The engineering applications of the experimental results are discussed.
