Reinforcing elements were driven horizontally and directly into the existing slope, similar to the installation of vertical wick drains, thus requiring little or no excavation. This results in a rapid and economical solution for slope stabilization. The reinforcing elements used in the model simulated the high-strength nonwoven geotextile strips, which will be used in actual slope remediation work. The geotextile strips perform the dual functions of drainage and reinforcement. Miniature drivers and various instrumentation were used in the models. The results from the model tests provide useful information for the design of the spacing and placement of the reinforcing strips and the design and construction of the actual prototype driving equipment. The proposed construction technique could be beneficial and economical in slope stabilization of highway embankments and related slope work in highway construction.
