What is deflection at the surface of a Rigid pavement due to wheel load of 40kN and a tyre pressure of .5MPa? The value of E for pavement and subgrade is 20MPa.

Modulus of subgrade reaction using 30cm diameter plate is obtained as 200N/cm³. The value of the same using standard plate will be

A CC pavement is placed over a soil with coefficient of friction as 1.2. The length of the pavement between two successive contraction joint is 2m. If the density of concrete is 2400 kg/m³, the frictional stresses developed during peak winter is:

In plate load test, pressure on soil is 40 kg/cm². The corresponding deflection,. Determine the modulus of elasticity of soil if the diameter of the plate used is 30cm.

The maximum spacing of expansion joints in rigid pavements l_e is given by:

Burmister considered the pavement structure as a homogeneous half space. Here the half-space means:

The critical combination of stresses for corner region in cement concrete roads is

A 3.5 m wide slab is having a thickness of 25 cm and the friction factor (f ) is 1.5. The length of the slab is 4.5 m and the unit weight of concrete is 2500 kg/m, stress developed due to seasonal variation is ________ N/mm².

If d is the thickness of a concrete pavement the equivalent radius b of resisting section for an interior loading is

If the load Stresses are 24 kg/cm², warping stresses are 30 kg/cm² and frictional stresses are 25.5 kg/cm², then what would be the value of critical stresses combination (in kg/cm²) at edge region during summer mid-day?
