This information sheet describes our recommended practices for the restoration of utility trenches cut into concrete pavements.
It includes details on planning the utility cut location, size and shape; making the necessary cut(s) in the concrete slab; removing the concrete; excavating the subbase and/or subgrade; repairing/upgrading or installing the utility; backfilling and compacting or placing flowable backfill; installing necessary embedded steel (dowel bars and tiebars); placing, finishing, texturing and curing the new concrete surface course; jointing and joint sealing; and opening to traffic.
Other design considerations such as precast panels, emergency patching, utility cuts in heavy-duty concrete pavements, utility cuts in concrete overlays, and utility cuts in pervious concrete pavements also are discussed.
