Research on the Test of Shear Strength and Dynamic Deformation Characteristic of Saturated Rubber Sand
Using waste tires as road engineering filler is an effective measure to deal with waste tires.In order to study the application potential of waste tire rubber particles and sand mixed soil in road engineering,this paper takes rubber sand as the research object,and discusses the influence of rubber particle content on the shear strength and dynamic deformation characteristics of saturated rubber sand through direct shear test and dynamic triaxial test.The results show that the shear strength,cohesion and internal friction angle of saturated rubber sand increase with the increase of rubber content;the maximum dynamic shear modulus of saturated rubber sand decreases with the increase of rubber particle content;when the content of rubber particles increases,the attenuation of dynamic modulus ratio of rubber sand becomes slower.The research results can provide reference for the engineering application of rubber sand.
