This thesis presents the results of a laboratory investigation of the relationship between the consistency limits and the moisture content as obtained by the moisture tension method. Thirty-eight soils from Indiana were used in this investigation. The ceramic plate apparatus was used for the moisture tension method. The effect of method of preparation of soil samples on the moisture tension method results was evaluated. The reproducibility of both the standard ASTM test and the moisture tension method results were studied. The results of this investigation indicated that a linear relationship exists between the consistency limits(LL and PL) and the moisture content, WCi, obtained at various pressure intensities, (6, 10, 12 and 18 psi).The results of the study strongly suggest that the moisture tension test can be used on a routine basis for determining the consistency limits of soils.
