Development of In Situ Cyclic Borehole Shear Soil Test Device

Static soil shear strength parameters in the form of friction angle and cohesion are required inputs for the safe design of foundations and earth retaining structures for virtually all transportation infrastructure including bridges, buildings, railways, wharves, piers, ports, tunnels, and pavements.

The TRB Highway Innovations Deserving Exploratory Analysis (IDEA) Program's Development of In Situ Cyclic Borehole Shear Soil Test Device develops a device designed to enable the rapid in situ measurement of cyclic behavior and monotonic shear strength properties of soil.
