Abstract
An integrated mobile test system and methods for characterizing in situ stress or strain/deflection—dependent stiffness and bearing capacity enables the testing of engineering properties of natural, compacted, stabilized, and reinforced soils and geo-materials. The mobile test system and associated methods (1) prepare the ground for testing and (2) apply static or cyclic loading to one or more bearing plates of various geometries positioned at the ground surface or below the ground surface to determine both stress and deflection dependent stiffness relationships and the bearing capacity of the soil or geo-material. Optionally, the mobile test system and associated methods (3) apply ground confining stress conditions independent of the bearing plate loading.
