Shear Modulus of Gravels.
Abstract
Nineteen samples of various granular soils and aggregates, most contraining gravel, were tested; 16 tested with a large resonant column device for testing 6-in. diameter by 12-in. long samples and three tested with a smaller resonant column device for testing either 1.4-in. or 2.8-in. diameter by 3-in. long samples. The variation of shear modulus with shear strain amplitude was studied. Previously developed relationships between shear modulus and shear strain amplitude, applicable to soils with sand size particles and smaller were expanded to define the relationships measured for gravels. At smaller strain levels the shear modulus of gravels was larger than for the smaller particle size previously tested, but decreased more rapidly with increasing shear strain amplitude. For graded materials, D5 = size with five percent finer was the significant size in determining the shear modulus at small strain amplitudes. (Author)
