Abstract
The Iowa DOT Soils Design section participated in the Demonstration Stage of the Advanced Geotechnical Exploration Methods (A-GaME) initiative. The A-GaME initiative sought to promote the use of advanced geotechnical methods as a means to reduce cost in subsurface investigation. One of the proven geophysical methods promoted is known as Electrical Resistivity (ER). In response to the A-Game Initiative, the IDOT Soils Design Section has investigated electrical resistivity (ER) as a novel technique to aid with subsurface investigation. Soils Design proposed to apply ER to evaluate if the technology could result in: (1) a reduced number of borings, (2) an enhanced understanding of subsurface conditions and site variability, (3) identification of depth to bedrock, and (4) overall reduction in geotechnical subsurface investigation costs.
