• Abstract:
  This research involved improving the vertical in situ permeameter (VIP), a new apparatus developed in FDOT Project BDV31-977-23 for estimating in situ permeability, and validating the prior research results through statewide testing. The VIP is a unique wireless instrument that allows the engineer to estimate mean permeability at multiple depths relatively quickly compared to alternative test methods. The device’s retractable tip helps to mitigate issues associated with soil smearing and siltation that can generate inaccurate readings. Throughout the course of the research, multiple tests were run with the instrument at different locations throughout the state of Florida. The collected permeability data were subsequently compared to results obtained at each site using standard in situ test methods, historical statewide trends, and the degree of permeability expected based on soil types encountered. The comparative analyses indicated the VIP compares favorably with standard methods and is capable of efficiently and accurately measuring permeability at multiple depths throughout the state of Florida.
