Rigid and Flexible Pavement
Following are some examples of how rigid and flexible pavement differ:
Grain-to-grain contact moves the burden from the top to the bottom.
Slab action is used to transmit the weight.
minimal or insignificant flexural strength
strong flexural capacity.
There are no joints.
There are contraction and expansion joints available.
Low upfront costs, but substantial ongoing expenses.
Low maintenance costs yet a high initial cost.
It consists of layers for the base, surface, sub-base, and subgrade.
Base course, Concrete slab, and subgrade layers are all part of it.
Underlying layers receive the effects of deformation in the top layers.
Only the top layer of the concrete slab has been deformed.
more appropriate for building stages
Less suited for stage building.
Extremely minimal impact of temperature stress
affected by frictional forces and temperature
Consider the following statements regarding pavements
The assertions Temperature changes have a greater impact on rigid pavements than on flexible pavements, and Any deformation in the top layers of a flexible pavement is communicated to the layers underneath it, whereas with rigid pavements, any deformation only affects the top layer of the concrete slab because of slab or beam action.
