Abstract:There are many unmapped features under the state’s roadways that threaten them with major localized
collapse. The most common of these features are abandoned underground mines in the eastern part of
the state and sinkholes in portions of limestone bedrock. These catastrophic failures may cause loss of
life, traffic disruption and large repair expenses. Identifying roadway locations which are likely to fail
would allow remedial action to prevent the future failure. Methods to locate these locations need to be
inexpensive enough to allow widespread use, but focused enough to target very specific problem areas.
Geophysical survey techniques have the potential for meeting these requirements. Specific geophysical
techniques need to be developed, which will be effective in identifying the potential failure zones under
the conditions that prevail in Ohio.
