Guidelines for the Application of Ground Modification Methods for Highway Structures

Over the last half century, public transportation agencies have greatly increased the use of ground modification methods due to a need to use marginal sites with poor soil conditions for new construction purposes and to mitigate the risk of failure or the poor performance of constructed facilities. More recently, ground modification has been used to meet challenges associated with accelerating construction in difficult geotechnical circumstances. Design and construction methods, equipment needs, technical feasibility, and acceptance criteria have been widely implemented through products developed by the Federal Highway Administration (FHWA). Technical assistance provided through the FHWA has helped state departments of transportation (DOTs) in developing and implementing design and construction documents to govern the use of ground modification methods regionally. Most recently, the development and deployment of GeoTechTools as a solution-based web tool continue to support increased safe, reliable, and cost-effective use. Research is needed to develop consistent guidance to aid states in the implementation and use of ground modification methods for application on bridges, retaining structures, and other geotechnical features on transportation projects. The objective of this project is to provide performance-based guidelines for the selection, design, construction, and acceptance of appropriate ground modification methods for transportation applications.
