|It consists of a series of layers with the highest quality materials at or near the surface of pavement.
||It consists of one layer Portland cement concrete slab or relatively high flexural strength.
|It reflects the deformations of subgrade and subsequent layers on the surface.
||It is able to bridge over localized failures and area of inadequate support.
|Its stability depends upon the aggregate interlock, particle friction and cohesion.
||Its structural strength is provided by the pavement slab itself by its beam action.
|Pavement design is greatly influenced by the subgrade strength.
||Flexural strength of concrete is a major factor for design.
|It functions by a way of load distribution through the component layers.
||It distributes load over a wide area of subgrade because of its rigidity and high modulus of elasticity.
|Temperature variations due to change in atmospheric conditions do not produce stresses in flexible pavements.
||Temperature changes induce heavy stresses in rigid pavements.
|Flexible pavements have self healing properties due to heavier wheel loads are recoverable due to some extent.
||Any excessive deformations occurring due to heavier wheel loads are not recoverable, i.e. settlements are permanent.
