A creep testing system (CTS) is developed to simultaneously perform four consolidated-undrained triaxial creep tests on cylindrical specimens. The CTS consists of: triaxial cells; lever-arm loading mechanisms; cell pressure-control panel board; temperature-control water baths; load, pore pressure and deformation measuring devices; and data logger system. The testing program consists of a series of twenty five step-type creep tests which were performed on samples of kaolinite and slaked Cucaracha clay-shale. The influence of testing conditions, such as loading procedure, magnitude of consolidation pressure, overconsolidation and secondary compression, on the creep behavior of clays was investigated.
