Difference between rigid pavement and flexible pavement

*    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
