Problem 2 A flexible pavement carries a static wheel load of 60 kN. The circular contact area of the tire is 86,000 square mm and the transmitted load s distributed across a wide area of the subgrade at an angle of 45 degrees. The subgrade bearing value is 0.15 MPa, while that of the base is 0.50 MPa. Design the thickness of pavement and that of the base.

![Problem 2
A flexible pavement carries a static wheel load of 60 kN. The circular contact area of the tire is 86,000 square
mm and the transmitted load is distributed across a wide area of the subgrade at an angle of 45 degrees. The
subgrade bearing value is 0.15 MPa, while that of the base is 0.50 MPa. Design the thickness of pavement and
that of the base.
