Asphalt overlays are occasionally laid around distressed concrete to restore a smooth donning surface.[31] A disadvantage of this process is usually that motion from the joints amongst the fundamental concrete slabs, regardless of whether from thermal enlargement and contraction, or from deflection in the concrete slabs from truck axle loads, commonly brings about reflective cracks while in the asphalt.

In Versatile pavements, vehicular anxiety is transferred to subgrade by way of obtain to accumulate contacts with the mixture in the granular layout. These types of roadways have much less flexural toughness, and keep it up like a flexible sheet (such as bituminous roadways).In the case of rigid pavement, automobile masses are transferred to sub-grade soil by the flexural toughness from the pavement, as well as pavement work as a rigid plate.
In rigid or unbending, the vehicular site visitors load is moved via slab area, and the road or street behaves like an elastic plate laying on the thick or viscous medium.
