The rigid pavement is usually designed for edge stress and checked for corner stress.
The combination of stresses would lead to failure when the slab is ______
A cc slab of thickness 25 cm is constructed over a base of granular material with a modulus of reaction 8 kg/cm3. The maximum temperature differential between the top and bottom of the slab is found to be 20°C during summer day and night. The spacing between transverse joints is 4.5 m and the spacing between longitudinal joints is 3.5 m. The design wheel load is 5100 kg, radius of contact area is 15 cm, Poisson’s ratio is 0.13, modulus of elasticity is 2×105 kg/cm2, the thermal coefficient is 10 ×10-6 /°C and the coefficient of friction is 1.5. Using the above information, find the worst combination of stresses during mid-night.
What stresses are to be computed if critical combination during day time is to be found out?
What will be the critical combination of stresses at the edge during winter if the following stresses have been calculated for the pavement?Load stress = 35.67 kg/cm2Warping stress = 30.31 kg/cm2Frictional stress = 0.89 kg/cm2
The load stress is the least in which region?
A cc slab of thickness 20 cm is constructed over a base of granular material with a modulus of reaction 10 kg/cm3. The maximum temperature differential between the top and bottom of the slab is found to be 19°C during summer day and night. The spacing between transverse joints is 8 m and the spacing between longitudinal joints is 4 m. The design wheel load is 5100 kg, radius of contact area is 15 cm, Poisson’s ratio is 0.15, modulus of elasticity is 3×105 kg/cm2, the thermal coefficient is 10 ×10-6 /°C and the coefficient of friction is 1.5. Using the above information, find the worst combination of stresses at the edge of the pavement.
What will be the critical combination of stresses at the corner if the following stresses have been calculated for the pavement?Load stress = 30.50 kg/cm2Warping stress = 8.56 kg/cm2Frictional stress = 0.77 kg/cm2
