Cyclic strength of gravel
WebUndrained cyclic strength of gravelly soils has not been investigated so much as sands with regard to their density, particle gradings, etc., though they have … WebLaboratory Soil Testing. GTX's fully equipped laboratories perform more than 100 different soils tests to determine physical properties. We provide these services in support of all types of earthwork applications. Our automated equipment permits us to run any type of consolidation, triaxial, or direct shear test a client specifies.
