In the construction of a new E6 Expressway between Jaktøyen and Storler in Trondheim, Norway, lime-cement columns were used extensively as stabilization measures for slope cut works in the clay strata. Non-sensitive clay, about 5-10 m thick, overlying sensitive clay and quick clay down to a depth of 25 m were found at the site. Reverse column penetration tests (RCP) were adopted as one of the quality control measures of the lime-cement columns. This paper presents the results of the RCPs from one of the areas in the project and examines the possible increase in shear strength of the lime-cement columns with depth. The variability of the RCP test results are also discussed.
