Synthesis of Information Related to Highway Practices. Topic 50-01. Advancements in Use of Geophysical Methods for Transportation Projects

In 2006, the National Academies published NCHRP Synthesis 357: Use of Geophysics for Transportation Projects, which identified benefits and challenges of using geophysical methods in transportation. Some of the obstacles identified by the study were recognizing appropriate applications and conditions, defining the investigation’s scope, obtaining adequate data, and objective interpretation by qualified professionals. Issues that the study identified included improving education and training, as well as the need for standards and training resources. Since publication of this Synthesis, however, there have been improvements with the hardware and software used for geophysical methods and techniques. The purpose of this synthesis is to provide an updated matrix of geophysical techniques for each application, as well as to provide background and training resources for geophysical methods that have consistently yielded quantifiable value through improvements to design efficiencies and reductions in construction risks. The synthesis should assess changes in the state of practice since publication of Synthesis 357 and include downhole methods and developing technologies. The synthesis would help identify the available tools and how the agencies can overcome obstacles to utilization.   Information will be gathered by literature review which identifies the most relevant examples, techniques and conditions under which consistent results are achieved. Surveys and/or interviews of the state DOTs and Canadian provinces and a minimum of five case examples shall be included.
