Calculate the settlement at max pressure as applied settlement at max load minus by settlement at seating load. Plot load intensity versus average settlements curve for each increment of settlement show in figure 1 to figure 3
The load intensity-settlement curve, calculate the modulus of subgrade reaction (k’u) for each by dividing the unit load at 69.0 kPa.(10 PSI.) and average deflection, the k’u value are show in the table 1. below
