The Geotechnical Section of the Materials and Tests Division is responsible for performing geotechnical investigations and providing recommendations for the design and construction of roadway and structures for the Indiana Department of Transportation. Geotechnical investigations include soil borings, sampling, testing, and engineering analyses for the purpose of evaluating the subsurface conditions inorder to provide recommendations for a suitable and economical foundation design.

This section is also responsible for the review of geotechnical reports prepared by a geotechnical consultant for all federally funded local agency projects.

In addition to geotechnical investigations, the section also handles all issues relating to Geotechnical Engineering for the INDOT. These issues may include:

  • Structure Foundation (pile driving systems, proof testing of rock, light weight fill, integrity testing, etc.)
  • Embankment (light weight cellular concrete, reinforced earth, shale, use of waste products, slope stability, etc.)
  • Ground Modification (stone columns, lime/cement/flyash, dynamic compaction, etc.)
  • Landslide (investigation, monitoring, and correction)
  • Geogrid and Geotextile
  • Other issues such as sinkhole, mine subsidence, retention/detention pond, peat/marl problem, erosion control, instrumentation, settlement
  • Prepare Standard Specifications and Special Provisions for geotechnical issues
