Investigation of Voids/Cracking on the I-275 Twin Bridges over the Ohio River in Kenton County Phase I

摘要

An evaluation of the northbound bridge approach and the abutment wall of (Combs-Hehl) bridge on I-275 in Kenton County was conducted in September 2007. The inspection consisted of using ground penetrating radar to look for potential voids beneath the concrete approach slab and a video camera inspection to inspect the void space beneath the pier cap/concrete beam in front of the abutment wall.
