Application of Geophysical Methods to Highway Related Problems....

Welcome to the Federal Highway Administration online geophysical imaging resource site.

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 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.

This website is divided into two main parts. The first part presents a range of transportation related problems that geophysical imaging and NDT methods can be used to solve (ENGINEERING APPLICATIONS). The second part provides the reader with in depth knowledge of geophysical methods and theories (GEOPHYSICAL METHODS).

It is recommended for the reader to start at the SOLUTION MATRIX to better navigate the website structure. For general information about this web manual go to ABOUT THIS SITE.
