There are so many merits of waste tire shred-sand mixture. Presently

it has been used as light filling. Series of shear tests of tire shred-sand mixture have been done; and the influence of different factors on shear performance is discussed

such as shred content

aspect ratio and compactness. The results show that it is nonlinear of the mixture Mohr-Coulomb envelope. The shear strength and friction angle increase with the tire shred content increase and the nonlinear behavior becomes more evident as the addition of the tire shreds. The friction angle of the mixture can increase by 8%-89% by means of optimizing shred aspect ratio

shred content and compaction. There is very little effect of shred width on shear performance. But the aspect ratio of the shred has obvious influence on shear behavior at other things being equal. There is one and only length for a fixed width of the tire shred

which can make the maximum friction angle of 65°.
