Advancements in Use of Geophysical Methods for Transportation Projects
Geophysical
methods provide a means to rapidly and economically characterize subsurface conditions and
infer soil properties over a spatial extent that is not possible with conventional methods.
The TRB National Cooperative Highway Research Program's
NCHRP Synthesis 547: Advancements in Use of Geophysical Methods for Transportation Projects
evaluates the current state of practice in the use of
geophysical methods by state transportation agencies.
Challenges and obstacles remain that must be overcome if routine implementation
of geophysical methods for transportation projects is to be realized.
Uncertainties associated with insufficient or poor site characterization
can lead to overly conservative designs, increased risk of poor performance, cost increases
attributable to changed conditions, and project delays.
