The magnitude of the pre-construction soil overburden pressure is 68 kPa at the center of the layer. A laboratory compression tests indicates that the clay is overconsolidated with a preconsolidation pressure equal to 80kPa. The value of the compression index, Cc=0.30 and the swell index is 0.05. The void ratio of the clay is 1.50.
