A relatively inexpensive system has been developed for applying repeated axial loading to test specimens in the existing triaxial equipment used for studying the strength behavior of stabilized andor compacted soils at confining pressures up to 1000 psi. Two independent systems were constructed and each system can subject three triaxial test specimens to about the same cyclic loading. The equipment has been operational for about one year, during which time it has proven to be simple and reliable to operate. Instrumentation for monitoring and recording loads, deformations, and pressures during repeated loading has also proved to be satisfactory with the exception of the load cells located inside the triaxial cell chambers. Preliminary test results using this equipment on a cement-stabilized silt show that repeated loading does not have a detrimental effect on the frictional resistance of this soil at ultimate but can partially destroy the cohesive resistance at the Mohr-Coulomb failure condition.
