The maximum wheel load that the pavement could carry is 120 kN. If the contact radius of the wheel is assumed to be 250 mm, and subgrade bearing capacity is equivalent to 0.24 Megapascals, calculate the subgrade layer thickness of the flexible pavement in mm using the 45-deg cone pressure distribution method.
