The purpose of crack & seat of pavement prior to overlaying it is to minimize the occurrence and severity of reflection cracks in the overlay caused by slab action by cracking the slabs to reduce their effective length and then seating the cracked slabs to reestablish support between the subbase and the slabs.
Reflection Cracking - Pavement Interactive
Description. Cracks in a flexible overlay over an existing crack or joint. The cracks occur directly over the underlying cracks or joints. “ Joint reflection cracking ” specifically refers to reflection cracks arising from underlying PCC pavement joint movement. Reflection cracks can also occur over existing HMA pavement cracks, cement or lime stabilized base, etc.
