Project Objective

To identify, observe and document geotechnical related problem situations that are present across the state.

Project Abstract

To identify, document, and prioritize significant problems having to do with earth materials, such as slope instability, soil erosion, and roadway subgrade instabilities, in Missouri transportation facilities and adjacent rights of way through visits to all MoDOT districts. While all geotechnical related problems will be considered, particular emphasis will be placed on evaluating the effectiveness of recently implemented designs for bridge approach slabs and pavement edge drains. A report documenting and prioritizing geotechnical problems, and evaluating the effectiveness of recently implemented designs, will be provided to MoDOT state and district level personnel, along with recommendations for approaches to research which could be applied to solve problems identified.

Task Description

It is envisioned that the proposed research will lead to field-useable design guidelines that would prevent, or at least delay, the onset of brittle failure so that the full strengthening potential of FRP plates may be realized.

Anticipated Benefits

The final report will provide MoDOT state level and district level personnel with a document detailing the nature, extent and distribution of Geotechnical related problems around the state.
