Completed Study
Training for Seismic Refraction Instrument to Determine Bedrock Depth beneath Roads
Jeffrey G. Paine, principal investigator
The Texas Department of Transportation (TxDOT) uses many instruments to monitor the condition of the extensive network of Texas highways. Depth to bedrock beneath roads is one of the more important parameters in assessing pavement condition. In this project, funded by TxDOT, we trained TxDOT staff to use the Seismic Refraction Bedrock Analyzer (SRBA), an instrument we developed and built to determine bedrock depth and material properties beneath pavement using seismic refraction methods. We conducted tests and training sessions at sites around the state, including in the Austin, San Antonio, Midland, Abilene, Brownwood, and Waco districts.
