Geotechnical

The purpose of this section 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 web manual 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.
