Abstract:ODOT District 10 personnel noticed signs of on-going problems (cracks, backfill washout) on the bridge abutment walls existing at the SR 33 bridge over E. State St. in Athens, Ohio (shown in Figure 1). The Ohio Research Institute for Transportation and the Environment (ORITE), Ohio University, received a contract to monitor the field performance of these abutment walls because of its past experience in monitoring abutment walls and the project site’s close proximity to the Ohio University campus. The ORITE researcher utilized a sensitive tilting measurement system to record the rotational movements of the abutment wall panels existing the site at least monthly. Also, other methods such as cone penetration tests (CPT) and visual inspection technique were employed to obtain additional data to both verify the findings reflected in the tilt-meter sensor readings and/or gain further insights into the conditions existing at the project site.
