TRC1803 - Mapping Subsurface Conditions for Transportation Applications

The overarching objective of this research effort is to examine the applicability of using various geophysical methods to map problematic soil and rock conditions along highway alignments. Four sites will be tested (two in Phase I and two in Phase II) where shallow bedrock exists or where slope stability problems exist. The advantages, benefits, costs, and limitations of each geophysical method will be examined in Phase I of the project and the preferred geophysical equipment/method will be chosen and purchased as part of Phase II. In Phase ll, two sites will be tested to further examine the accuracy of the method and develop best practices for field testing. Finally, training and a testing guidebook will be provided to AHTD on the use of the equipment/method.
