Crack & seat has been widely used since the early 1980’s to reduce the extent and severity of reflective cracking in asphalt overlays placed on concrete pavements. This video from 2012 shows the crack & seat process performed by Antigo Construction on Interstate Highway 90 in Mineral County, Montana. A T8600 Badger Breaker® drops its hammer approximately every 24 inches to induce hairline cracks through the depth of the concrete slab while maintaining good aggregate interlock between the cracked segments. Antigo cracked & seated 342,112 square yards of 9â€ thick, jointed plain concrete pavement on this project. The gold at the end of this rainbow is a smooth asphalt road for many years to come.
