The selection of an appropriate geoconstruction technology to use in transportation systems is a complex undertaking that depends upon integration of available knowledge and a number problem-specific and site-specific factors. A web-based information and guidance system, Geotechnical Solutions for Transportation Infrastructure, was developed to access critical information on geoconstruction technologies and to provide a tool to assist in deciding which technologies are potentially applicable to site-specific conditions. The system is based on three project elements: (1) construction of new embankments and roadways over unstable soils, (2) widening and expansion of existing roadways and embankments, and (3) stabilization of the working platform. Forty-six ground improvement and geoconstruction technologies and processes applicable to the three elements are included in the system. The system contains a technology catalog and a technology selection assistance tool, as well as sections on geotechnical design philosophy and a geotechnical glossary. Eight end-user products are available for each of the geoconstruction technologies in the catalog. The end-user products include: Technology Fact Sheets, Photographs, Case Histories, Design Procedures, Quality Control/Quality Assurance Procedures, Cost Estimating Tools, Specification Guidance, and Bibliography. The primary value of this web-based information and guidance system is that it collects, synthesizes, integrates, and organizes a vast amount of important information about geotechnical solutions in a system that makes the information readily accessible to State Transportation Agency (STA) personnel. This report describes the development details of the web-based information and guidance system. (Author/publisher)
