Q. Diffrence between Concrete road and bituminous road?
Concrete road belongs to rigid pavement and they don't deflect under traffic loads. Quite the reverse, bituminous pavement deflects when subjected to vehicular load. For concrete road no additional effort is paid on getting out of deflected ruts that is commonly encountered for bituminous pavement. Therefore vehicles using concrete road use less energy and there is about 15-20% less fuel consumed when using concrete road comparatively when using bituminous road.
