Abstract:
Sand-rubber mixtures has characteristics of light weight, cheap and environmental-friendly, thereby it has a great potential to be used in geotechnical engineering for sustainable development. Dynamic properties (i.e. shear modulus and damping ratio) of sand-rubber mixtures in a small range of shearing strain amplitudes (i.e. 10-6-10-4) were investigated in this study through a series of resonant column tests. The effects of shearing strain amplitude, confining pressure and rubber content on dynamic shear modulus ( G ), maximum dynamic shear modulus ( G m a x ), damping ratio ( D ) and dynamic shear modulus ratio G / G m a x of the mixtures were also discussed. Based on the analyses of the relationship among confining pressure, rubber content and G m a x , an empirical formula for predicting G m a x considering the effects of confining pressure and rubber content was also proposed. The model prediction agreed with the experimental results very well.
