Comparison between Bituminous (Flexible) & Cement concrete(Rigid) Pavements

Following Comparison between Bituminous (Flexible) & Cement concrete(Rigid) Pavements are described below:
let,

F = Bituminous (Flexible)Pavements.
R = Cement concrete(Rigid)Pavements.

F: Initial cost of construction is low for bituminous pavements.
R: Initial cost of construction is high for cement concrete pavement.


F: Life span is short.
R: Life span is long.


F: Construction joints are not required.
R: Construction joints are essentially required.


F: Moderate skill and less supervision is required.
R: High degree of skill and more supervision is required.


F: Repair work is easy.
R: Repair work is difficult.


F: They can be opened to traffic shortly after construction.
R: They can not be opened to traffic shortly after construction.


F: bituminous pavements are less durable.
R:  cement concrete pavement are more durable.


F: They are more resilient to traffic load.
R: They are less resilient to traffic load.

F: They offer more tractive resistance.
R: They offer less tractive resistance.


F: Their maintenance cost is high.
R: Their maintenance cost is low.
