Break & Seat

The purpose of break & seat of jointed reinforced concrete pavement (JRCP) prior to overlaying it is to minimize the occurrence and severity of reflection cracks in the overlay caused by slab action by breaking the concrete slabs to reduce their effective length and then seating the broken slabs to reestablish support between the subbase and the slabs. More fracture energy is employed than for crack & seat in order to sever the reinforcing steel thus causing more spalling of the concrete surface. Specifications typically require several passes with a proof roller to seat the broken concrete. Most break & seat has been performed with the T8600 Badger Breaker® although the MHB Badger Breaker® has been used in certain applications.
