Abstract:

Traditionally, highway agencies relied mainly on man-entry approach for assessing in-service conditions of their culverts. And, this direct approach left many drainage structures unapproachable and uninspected. This is because a large number of drainage structures are often small (diameter or rise less than 4 ft), inaccessible (entrance restricted by a catch basin or manhole, or entrance located at the bottom of a steep slope), or obstructed (filled with water or sediment). These undesirable culvert conditions are particularly common in Ashtabula County, where a majority of culverts range in diameter from 12 to 36 inches and are sometimes obstructed partially by sediment and/or water. In addition, the outlet ends of the drainage structures along the northern boundary of this county, draining to Lake Erie, are situated on steep unstable soil slopes. The main goal of the study was to identify for the ODOT Ashtabula County garage workforce remote culvert inspection technologies which are cost effective, easy and safe to operate, reliable, capable of performing post-installation inspections. After several months of extensive literature review, online data search, discussions with the Ashtabula County garage workforce, and discussions with TAC members, several promising remote inspection systems surfaced that are believed to be helpful for the Ashtabula County garage. These systems varied from small pipe crawlers, to larger multi-sensor platform units as well as micro UAVs. The team’s recommendations are accompanied with a set of decision three charts, system matrices, comparison tables, risk analysis, and cost analysis. The team also identified emerging technologies that need to be explored in the near future.
