* rigid pavement are constructed by cement , sand , aggregate ,Bars are also provided in rigid pavement .
flexible pavement are constructed by Bitumen coal tar.
* rigid pavement have high flexural strength.
Flexible pavement contains low flexural strength .
* Rigid pavement have initial cost is high.
Flexible pavement its initial cost is low.
* Rigid pavement have long life span .
Flexible pavement its have short life span .
* In the rigid pavement joints are required , joints are very necessary for rigid pavement because at the time of hot temprature stresses are create.
In the flexural pavement joints are not required.
* In the rigid pavement are not required high quality sub -grade .
In flexible pavement high quality sub- grade are needs.
* In the rigid pavement due to high temprature stresses are develops .
Stresses are not applicable for flexible pavement .
* Pot holes are not easily repair in rigid pavement .
Pot holes are easily repair in flexible pavement .
* more skilled engineers and well trained labour are required.
In the flexible pavement are not requirement of well educated ,and well trained labour .
* Rigid pavement are more requirement of time because after the construction of rigid pavement minimum (10-15) days of curing required.
flexible pavement are less requirement of time because its no needs of curing.
* rigid pavement are less resilient to traffic.
it is more resilient.
* rigid pavement are not adjust due to any deformation of sub-grade without rupture.
Flexible pavement are adjust due to any deformation of sub-grade without rupture.
* rigid pavement are not applicable for noisy under iron wheeled traffic.
Flexible pavement are suitable for all types of traffic.
* Rigid pavement maintenance cost is low
Flexible pavement its maintenance cost is high
