For this IDOT project, the scope consisted of geotechnical subsurface soil exploration including roadway soil borings, structure soil borings and pavement cores for the addition of lanes, intersection signalization, and resurfacing. Responsibilities included scoping subsurface investigations, laboratory testing, reviewing field data and laboratory test reports, attending project meetings, geotechnical analyses, preparation of Roadway Geotechnical Report (RGR) and Structure Geotechnical Reports (SGR) for retaining walls and box culverts in accordance with IDOT guidelines. Laboratory testing included moisture content tests and unconfined compressive strength tests, grainsize analysis, Atterberg limits, and Illinois Bearing Ratio tests.
