Original paper


A new comprehensive, web-based information system summarizes forty-six geoconstruction technologies, or ground improvement methods, applicable to transportation infrastructure from the following areas: geosynthetics, geotextiles, ground improvement, grouting, slope stabilization, soil reinforcement, soil stabilization, and alternative/recycled materials. Selection assistance was developed as part of the overall information system to aid the user in identifying potential geoconstruction technologies for a project-specific set of conditions. A knowledge base to assist a user in evaluating the current status of each technology with regard to the U.S. practice and the potential applications for each technology is described in detail. Selection assistance includes qualitative ratings for each technology, a listing of the technologies sorted by classification or desired improvement, and a dynamic, Interactive Selection tool. After assisting the user in identifying a short list of potential technologies, the user can access the technology specific data in the information system to further evaluate the technologies. Engineers, planners, and owners will be able to utilize the entire information system to assess the feasibility of technologies to address project-specific requirements and constraints.
