Q2: tire with 700 kPa air pressure distributes a load over an area with a circular contact radius, a, of 130mm. The pavement was constructed with a material that has a modules of elasticity of 345000 kPa &nd a Poisson ratio of 0.45 and thickness of 30cm. Calculate the radial-horizontal stress and deflection at a point the pavement surface under the center of the tire load. Also, calculate the radial-horizontal stress and deflection at a point at a depth of half pavement layer way from the centre of the tire load. (USE: Ahlvin and Ulery equations).
