Crack and seat treatment (Fmuhpc)

The process whereby the existing concrete pavement is cracked to destroy the integrity of the slab. This cracking reduces the slab length, which reduces the thermal effect on joint movement. The seating operation is required to ensure that the pieces of slab are firmly seated into the underlying foundation material to eliminate vertical movement. Both of these are contributing factors in the development of reflection cracking. Reduction in the amount and severity of reflection cracking in an asphalt concrete overlay is the sole design requirement of the crack and seat procedure on a rigid pavement.
