Abstract: As with all material testing, soils testing has undergone dramatic advances in technology because of computer automation. In the 1970s, laboratories were filled with dial gages, proving rings, mercury pots, and pressure regulators. It was an environment dominated by manual labor, imposing many constraints on test capability and duration. For example, collecting time-deformation measurements during all the increments of an oedometer test was an expensive venture.
