Difference Between Flexible Pavement And Rigid Pavement

Difference Between Flexible Pavement And Rigid Pavement

Flexible Pavement                                    

1. Load distribution (wide area)                         
2. Bituminous surface.                                              
3. Initial cost is less and maintenance cost is less.
4. Flexible pavement are laid are no joints.                                                            
5. Empirical method based on load distribution characteristics of the load components                                                            
6. Local depression.                                                      
7. Constructed in number of layers.                                                                        
8. No stress is produced.                                          
9. Less deformation in the sub grade is not transferred to the  upper layers.       
10. Road can be used for traffic within 24 hours.                                             
11.   Rolling of the strength is needed.                     

   Rigid Pavement

1.  Load distribution (wider area)                                                                                      
2.  Concrete surface.
3. Initial cost are high  and maintenance cost is less.
4. Rigid pavement are constructed in bays, hence joints are present.
5. Designed and analyzed by us  elastic theory. 
6. Causes cracks.
7.  Laid in slab with steel reinforcement. 
8. Stress is produced.
9. Friction force is high.     
10. Road cannot be used until 14 days of curing.
11.  Rolling of the surface is not needed
