The purpose of this website is to provide highway engineers with a basic knowledge of geophysics
and nondestructive test (NDT) methods for solving specific engineering problems during geotechnical
site investigation, construction, and maintenance of highways. The website is not intended to make
engineers experts in the field of geophysics, but rather to provide them with tools that will assist
them in the use of suitable geophysical and NDT techniques to evaluate problems for design, planning,
construction, or remediation efforts.
