CONSTANT-RATE-OF-STRAIN AND CONTROLLED-GRADIENT CONSOLIDATION TESTING

Controlled-gradient (CG), constant-rate-of-strain (CRS), and conventional incremental-loading (STD) consolidation testing are compared and evaluated. Undisturbed samples representing three soils common to Kentucky were used in the testing program. Settlements estimated by each testing technique were compared with settlement records from one of the sites. Results of 15 CG, 14 CRS, and 32 STD consolidation tests are shown. No significant differences were noted in values obtained from the three types of consolidation tests. Feasibility of the new test methods for routine testing is briefly discussed and recommendations were made for refinements in testing procedures.
