The consolidation properties of the soils are presented (which were determined from consolidometer tests) in this report of a study the objectives of which were to determine the compression index and the coefficient of consolidation, to investigate the effects of using back pressure to assure 100 percent saturation on the soil being tested, and to develop predictor equations for the compression index in terms of other geotechnical properties. Information is given on core extrusion and geotechnical tests. The results are illustrated (by graphs) and discussed. The compression index of the soils cannot be defined because the virgin compression curves are not linear, but concave upward on a semilog plot. The average overconsolidation ratio for 10 tests was 2.1. Ten samples were over overconsolidated. The coefficient of consolidation is calculated and predictor equations for compression index are presented. Two empirical predictor equations for the compression index were developed in terms of initial void ratio and intitial water content. It is concluded from the results of the study that back pressure consolidation are not necessary to define the compressibilities of Wilkinson Basin.
