F. PAVEMENT CORING
- Before acceptance of new pavement construction, drilled cores shall be obtained by the Engineer to verify compliance with pavement design thickness and concrete compressive strength specifications.
- Cores for depth shall be taken, with a minimum 2" diameter core bit, at the rate of one core for each 300 linear feet of two lane pavement. Additional cores shall be taken to represent turn lanes, intersections, and other areas as directed by the Engineer.
- If test cylinders indicate questionable compressive strength, cores shall be taken using a 4" diameter core bit to represent the concrete in question and shall be delivered to the City Testing Lab for compressive strength testing.
- All core holes shall be filled immediately after cores are removed with a commercially produced concrete mix product approved by the Engineer.
- Reports of all coring shall be submitted to the City Coordinator.
