This project, as part of the FHWA Demonstration Projects Program was intended to demonstrate the practicality, cost effectiveness, and esthetics of reinforced earth structures in highway construction. The reinforced earth concept was developed in France and consists of reinforcing earth with horizontal elements extending from a thin facing (concrete or steel) into a granular backfill to form retaining walls or other types of supporting structures. This report describes the first six retaining structures built on highway projects in the U.S., the first bridge abutment and the first foundation slab supporting an embankment in a sinkhole prone geological area. Construction techniques and equipment are discussed as well as costs for each project. Pictures of completed walls illustrate the esthetics of this concept. This demonstration project has shown that savings in the order of several hundreds of thousands of dollars have been realized on several of the projects described when compared to alternate retaining systems currently available to engineers. The potential for further savings is significant in future highway design. Illustrations of some possible design concepts are presented.
