Crack and Seat is a cost-effective process used prior to pavement resurfacing that reduces the occurrence of
reflection cracks
in the overlay. Reflection cracks can occur over time in the asphalt
layer that is paved over concrete panels. These cracks occur from
movement in the joints between the concrete panels.
The process of Crack and Seat involves cracking the concrete slabs to
reduce their size and make the rigid panels more flexible, before
seating them to reestablish support.
