involves reinforcing steep slopes. With the use of geosynthetics, the construction of reinforced steep slopes is often more affordable and technically feasible when compared to traditional construction techniques (Holtz, 2003). Furthermore, geosynthetic reinforcement is a cost effective solution for stabilizing recurring slope failures and constructing new permanent embankments (Leshchinsky et al., 1995; Rowe and Jones, 2000). 5 ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! !

Florida DOT (2010) Place the geosynthetics used for slope stabilization such that its primary direction of tensile strength is perpendicular to the plan face of the slope. Pull the material tight and secure it as necessary to lay flat against the soil prior to fill placement. Place only that amount of geosynthetic material, including facing and drainage material, which will be covered in a single day’s production. Mississippi DOT (2004) Geogrid shall [...] to optimize the use of geosynthetics. Furthermore, to apply the technology and techniques in an effective manner, it is critical to determine the factors leading to the successes and failures of GRSS, including the investigation of site conditions, material properties, design methods and construction practices.

## Slope Stabilization Using Retaining Wall Geogrid
ACE provides geosynthetic solutions that reinforce slopes and prevent erosion. The angle of repose is a critical factor in geotechnical engineering, and reinforcement becomes especially important as the slope angle increases. Products like ACEGrid® geogrids and ACETex® geotextiles are engineered to support a range of slope geometries, especially at steeper angles where reinforcement is crucial. [...] Embankments are a common application for slope stabilization in civil and geotechnical engineering, as they require reinforcement to maintain stability. Slopes and embankments can fail due to instability, leading to collapse or landslides caused by factors such as steep gradients, poor soil, or heavy loads. Techniques like retaining walls, soil nailing, and geogrid reinforcement are commonly used to stabilize slopes and embankments and protect infrastructure. Drainage plays a key role, as [...] Slope stabilization methods fall into two categories: external and internal. External techniques include retaining walls and anchors that directly support the slope. Retaining walls can be constructed from different materials, such as concrete blocks, rocks, or timber, and the choice of material affects the wall's design and stability. Internal methods, such as soil nailing or geogrids, enhance soil strength from within. Uniaxial geogrids reinforce soil in one direction, ideal for retaining

Geosynthetics are modern materials used to improve soil conditions by providing tensile resistance and stability. In the case of soil reinforcement, a primary application of geosynthetics involves reinforcing steep slopes. With the use of geosynthetics, the construction of reinforced steep slopes is often more affordable and technically feasible when compared to traditional construction techniques . Furthermore, geosynthetic reinforcement is a cost-effective solution for stabilizing recurring [...] Geosynthetic reinforcement of steep slopes was initially utilized to repair failed slopes. Instead of importing soil to reconstruct the slopes, the slide debris was salvaged and reused with the addition of geosynthetic reinforcement, resulting in reduced costs. To provide stability, multiple layers of geosynthetic materials were placed in a fill slope during reconstruction. As per Figure 1, in addition to repairing failed slopes, steep slope reinforcement has also been introduced for the [...] Reinforced slopes are a form of mechanically stabilized earth that incorporate planar reinforcing elements for the construction of sloped structures with inclinations less than 70°. Structures with inclinations over 70° are classified as walls . For uniform fill soil, there is a limiting slope angle under which an unreinforced slope may be built safely. The limiting angle of the slope is equal to the friction angle of the soil in the case of a cohesionless and dry material. Therefore, a slope

Geosynthetic Reinforced Embankments September 2023 Page 1 of 17 1 Reinforced Embankments Geosynthetic Reinforced Embankment (GRE) is a system that incorporates planar geosynthetic reinforcement within a slope (Figure 1) for slope inclinations less than 70 degrees from horizontal. A GRE is also referred to as a Reinforced Soil Slope. Situations where GRE may be used include: • • • • Limited right of way Shortage of fill quantity for slope construction Excess of excavated materials Distressed or [...] geogrid and biaxial geogrid. Place geosynthetic reinforcements horizontally. Select a set of LTS from the table of primary geosynthetic reinforcements in the Standard Specifications section 96-1.02D(2) as shown below: Primary Geosynthetic Reinforcement • • • For slope heights less than 25 feet, use a set of at least 2 different geosynthetic reinforcements that allows for selection of 2 LTS during analysis and design. For slopes higher than 25 feet, use a set of at least 3 different geosynthetic [...] geosynthetic reinforcements, with a set of 3 or more LTS can be selected for analysis and design. Adjust geosynthetic reinforcement lengths according to stability demand. Reduce the reinforcement lengths toward the top of the slope as the demand reduces. The reinforcement lengths must be at least 8 feet.
