• Abstract:
  Surveys, interviews and site visits were used to identify, observe and document geotechnical-related problems in Missouri DOT infrastructure. Documented issues were evaluated and prioritized. Additional attention was focused on Pavement Edge Drains and Bridge Approach Slabs since new designs for both were instituted in the early 1990's. In general, issues did not merit critical consideration until they impacted the pavement. The most critical issues include slope stability (soil), pavement (stability, sub-base support, drainage), erosion control (on new construction and long-term facilities) and bridge approach slabs. Half of all the issues, including all of the critical ones, involve excess or uncontrolled water. Long-term performance monitoring should be initiated on the most critical issues in order to develop a baseline of performance, identify the root causes of poor performance and provide for 'evidence-based' redesigns where necessary. Some of the problems identified result directly or indirectly from a succinct discontinuity of the role of the geotechnical unit throughout the design, construction and maintenance operations of MoDOT.
