Test: Stresses in Rigid Pavements - Question 1

Major stresses in CC pavement is

Detailed Solution for Test: Stresses in Rigid Pavements - Question 1

The major stress is caused due to wheel load and temperature, remaining all are the minor stresses.

Test: Stresses in Rigid Pavements - Question 2

 The unit of ‘K’ is

Detailed Solution for Test: Stresses in Rigid Pavements - Question 2

The modulus of sub grade reaction is the pressure per deflection unit, it was obtained by Westrergaard for deflection analysis.

Test: Stresses in Rigid Pavements - Question 3

The deflection in Westergaard analysis is

Detailed Solution for Test: Stresses in Rigid Pavements - Question 3

The deflection is assumed as 0.125 in Westergaard analysis, it is constant value for the deflection for modulus of sub grade reaction.

Test: Stresses in Rigid Pavements - Question 4

The Poisson’s ratio of concrete is

Detailed Solution for Test: Stresses in Rigid Pavements - Question 4

The Poisson’s ratio of concrete is mostly assumed as 0.15 however it may lie between 0.13 and 0.15.

Test: Stresses in Rigid Pavements - Question 5

The deflection of slab is dependent on

Detailed Solution for Test: Stresses in Rigid Pavements - Question 5

The deflection is dependent on the flexural strength of the material on how it breaks.

Test: Stresses in Rigid Pavements - Question 6

The stiffness of slab mainly depends on

Detailed Solution for Test: Stresses in Rigid Pavements - Question 6

 The radius of relative stiffness mainly depends on the soil sub grade reaction.

Test: Stresses in Rigid Pavements - Question 7

.If any load is placed at interior away from all edges then it is called

Detailed Solution for Test: Stresses in Rigid Pavements - Question 7

The loading that takes place inside of the pavement away from all edges is called as interior loading.

Test: Stresses in Rigid Pavements - Question 8

 The loading which does not exist is

Detailed Solution for Test: Stresses in Rigid Pavements - Question 8

The loading that doesn’t exist is exterior loading because a load cannot be outside of pavement.

Test: Stresses in Rigid Pavements - Question 9

The distance at which the crack is developed is given by

Detailed Solution for Test: Stresses in Rigid Pavements - Question 9

The distance is given by the equation 2.58al, where a is the radius of wheel distribution and l is radius of relative stiffness.

Test: Stresses in Rigid Pavements - Question 10

Warping stress coefficient charts were prepared by

Detailed Solution for Test: Stresses in Rigid Pavements - Question 10

The charts were prepared by Bradbury, assuming it depends on seasonal coefficient and radius of relative stiffness.
