A report that examines the impact that new AASHTO design requirements may have on connection details in mechanically stabilized earth walls.

Self-consolidating concrete (SCC) is a stable and highly flowable concrete that consolidates without the help of external vibration and can flow through heavy reinforcement and around corners in complex formwork under its own weight. The exceptional performance of this remarkable material has attracted the attention of construction firms and DOTs in the United States interested in using SCC on new bridge construction and bridge repair projects.

This study determined the feasibility of using driven piles to stabilize highway embankment slopes. The activities performed under this study were a detailed literature review, a national survey of state DOTs, a review of inspection and stabilization mitigation reports, targeted field inspections, a cost comparison analysis, and a finite element study. The results of this study show that driven piles can be a cost-effective solution to stabilizing...
