A precast concrete retaining wall has been developed for the Colorado Division of Highways to retain highway embankments in a manner that will minimize the base width of embankments to avoid stream encroachment and reduce the area of natural terrain obliterated. The precast concrete elements are so designed as to facilitate rapid field erection and minimize the requirements for skilled labor. The analyses required soils mechanics assumptions not previously substantiated. To verify the assumptions a full scale wall was erected, instrumented and tested. The test program confirmed the accuracy of the design and provided a visual illustration of the aesthetic qulaities of the wall. Unit costs are erection times were also confirmed through the test program. Since the retaining wall represents an innovation in this type of structure movies were made of the fabrication and erection for the benefit of the contractors in the preparation of their bids. A full report of the analysis, design, test procedures, and results is available.
