Book excerpt: Mechanically stabilized earth (MSE) has been used for over thirty years in the United States. The advantages of MSE, including economics, often out weigh their disadvantages. MSE structures are built with a growing frequency and are not likely to disappear in the foreseeable future. Complete understanding of the system has not yet been widely achieved. This thesis is a study of the movement and deformation during construction of a mechanically stabilized earth structure built as a bridge abutment. The MSE wall studied for this research was constructed as part of an ODOT bridge replacement and widening project located in northwest Ohio. The studied MSE system for this project was a Reinforced Earth Company product. The subsurface conditions under the main MSE wall face include an approximate twenty foot thick clay layer over limestone bedrock. Phased construction was used along with both cast in place and precast leveling pads. Some wall facing deformations presented are expected, while others are more difficult to explain. Results of this research provide information that can be used to better understand deformation during the construction process of similar walls constructed in the future. Comparison of these results to performance of other MSE walls may ease concerns of possible larger problems. Further similar work is likely needed to explain some of the trends presented here.
