Abstract:Geosynthetic reinforced steep slopes (GRSSs) are a form of mechanically stabilized earth that incorporates polymeric reinforcing elements for the construction of sloped structures with inclinations less than 70 degrees. Geosynthetics provide a means to improve tensile resistance and stability in steep slope applications while also accommodating budgetary restrictions and alleviating space constraints. In addition to repairing failed slopes, geosynthetics have also been introduced for the construction of new embankments, for the widening of existing embankments, and as an alternative to retaining walls. The Texas Department of Transportation (TxDOT) currently has limited use of geosynthetics for steep slope reinforcement, and to sufficiently employ this construction technique, knowledge of soil conditions, slope geometry, design criteria, construction sequence, and performance is required. Therefore, a synthesis study on GRSSs was conducted to enhance the present understanding of this technology.
