2Durability is less as compare to rigid.Durability is more as compare to flexible.
3Road can be used within 24 hours.Road cannot be used until 14 days of curing.
4Low flexural strength.  
*(Flexural strength is one measure of the tensile strength of concrete. It is a measure of an unreinforced concrete beam or slab to resist failure in bending.)		High flexural strength.
5Road Rollers are used.Road Rollers are not used.
6No thermal stresses are induced.Thermal stresses are induced.
7Strength depends on subgrade.Strength does not depends on subgrade.
8It consist four layer system(i.e. soil subgrade, sub base course, base course and surface course).It consist three layer system(i.e. soil subgrade, base course and surface course).
9Deformation in subgrade or lower layers transferred to upper layers.Deformation in subgrade does not transferred to upper layers.
