Oklahoma DOT Guidelines for the Use of FRS in Highway Construction

Transportation agencies in the U.S. are continually faced with a persistent problem of landslides and slope failures along highways. Repairs and maintenance work associated with these failures cost these agencies millions of dollars annually. Several recent studies and fairly extensive field experience have shown that Fiber-Reinforced Soil (FRS) technology can result in significant cost savings in highway construction projects in addition to other advantages such as reduced carbon footprint by allowing the use of locally available soils, and lower susceptibility to weather conditions as compared to other methods such as chemical stabilization. However, despite these advantages and the fact that to date more than 100 FRS projects have been constructed in the U.S., there are currently no commonly-accepted and reliable guidelines available for the use of FRS in highway projects. Therefore, there is a need for the transportation agencies to update and improve their construction guidelines and specifications to include a wider range of newer and promising technologies such as FRS that could help them meet the increasing demands on the transportation infrastructure at the time of limited budgets and available resources. This study is aimed at addressing this need in Oklahoma and other states across the U.S. by developing guidelines for the FRS technology in collaboration with the Oklahoma Department of Transportation, which will be in alignment with other major efforts and initiatives by the state and federal agencies to increase stakeholders’ access to technologies that have been proven to be reliable and cost-effective. The main objective of the study is to develop analysis and design tools for stability calculations of FRS highway embankments using locally available soils together with guidance manual and specifications for their proper construction. A set of case histories on major FRS projects to date will also be provided.
