Question

Calculate the stress at interior, edge and corner region of a cement concrete pavement

weslergaard’s stress equations use the following data

Wheel load = p = 5100 kg, modulus plasticity of cement concrete =3× 105 kg per centimetre

square pavement thickness =18 centimetre, poison is ratio of concrete = 0.15

Modulus of subgrade reaction, k =6.0 kg/cm3

radius of contact area =a =15 centimetres​
