The radius of the contact area can be found out using the relation between wheel load (P), tyre pressure (p) and radius (a) as πa2 = P/p. So, the radius of the contact area can be obtained as 
In order to find subgrade support, perimeter area ratio and the plate load test details are required. The perimeter area ratio can be obtained as
The design chart defined by Norman W. McLeod through the Canadian Department of Transport is used. A sample is shown below with the details for 0.5 cm deflection. The ratio for subgrade is obtained as 1.1 from the same.
Therefore, the design subgrade support is = Ratio obtained from chart X contact pressure of design load = 1.1 X 2.5 = 2.75 kg/cm2.
