The popular theories currently used to estimate earth pressure1,2 were developed many years ago3. Although these theories are considered appropriate for many earth pressure problems, they may not be suitable to determine the earth pressures developed from or transferred through reinforced soil walls and abutments. Estimates for earth pressures, from reinforced soils, acting on structural facings are considered especially important. A new large scale testing apparatus is developed to study the behavior of reinforced fill walls and abutments, especially for the development and distribution of earth pressures. The concept, design, construction, preliminary testing, and future plans for this testing system are presented in this paper.
