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°. To provide tensile resistance and stability, geosynthetic reinforcement has been employed for repairing failed slopes, constructing new embankments, and widening existing embankments. [...] Geosynthetics are modern materials used to improve soil conditions by providing tensile resistance and stability.

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 ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! [...] in steep slope construction. Therefore, a synthesis study of geosynthetic reinforced steep slopes has been conducted to enhance the present understanding of this technology. The study summarized the benefits and limitations of utilizing geosynthetic reinforcement and investigated current design and construction methods in order to determine best practices. Additionally, the cost effectiveness of geosynthetic reinforced steep slopes was examined. Case studies were also identified and assessed to [...] 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.

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 [...] Distressed or deteriorated slopes need to be restored. The components of a geosynthetic reinforced embankment include: geosynthetic reinforcements, reinforced soil, drainage system, and erosion control. The foundation below the GRE (foundation soil) and slope behind the GRE (retained soil) also affect the design of the GRE.

If necessary, one traffic lane may need to be closed during construction. Processed landslide debris may be used as reinforced soil if sufficient geosynthetic reinforcements are used, the reinforced soil materials do not cause creep, and proper subdrain is designed. To keep the slope dry, prefabricated vertical drains may be placed horizontally in conjunction with the geosynthetic reinforcements. 5 Execution and Communication During Design During design, close communication

Built as earth retaining structures, slopes are constructed to an angle to horizontal typically between 45° and 76°. These reinforced soil structures are commonly referred to by engineers as Reinforced Soil Slopes (RSS) or Geosynthetic Reinforced Slopes (GRS). Geoquest’s success in this field has led to solutions that have reached a world record-setting RSS structure being built to a height exceeding 100m.

Reinforced slopes that are 1(H): 1(V) and steeper typically require additional facing support during construction. A geosynthetic face wrap and/or a hard armor facing support system is often employed in these scenarios. Particularly when constructing slopes with materials like silts and poorly graded sands and gravels, or in environments subjected to external erosive forces such as mild water currents and/or wave attack, robust facing supports are essential. Temporary supports such as wooden [...] Geosynthetic materials, including geotextiles and geogrids, play a versatile role in RSS, enhancing structural support, facilitating drainage, and supporting vegetation growth. These synthetic solutions bridge the gap between soft and hard facing options for reinforced slopes, offering tailored reinforcement that meets specific site requirements. They are particularly valuable in environments subjected to dynamic weather conditions and hydraulic pressures, where traditional materials might fail [...] Reinforced soil slopes (RSS) stand as a cornerstone in modern geotechnical engineering, offering robust solutions for constructing slopes with inclinations less than 70 degrees from the horizontal. These structures are pivotal in combating erosion, facilitating vegetation growth, and ensuring the stability of steepened terrain. The general facing systems deployed in these constructions can be broadly classified into two types: soft or vegetated and hard armored systems, which may or may not

Within the past seven years, short geosynthetic fibers ( Geofibers have been successfully used on more than 25 slope projects in the United States. These projects have involved repairs of shallow slope failures, repair of deepseated slope failures, and veneer reinforcement in new slope construction to reduce future maintenance costs. These fibers also have tremendous potential for use as veneer and secondary reinforcement in geotextile - fibers composite reinforcement of slopes. This [...] of slopes. This combination of geosynthetics has the potential to virtually eliminate any significant future maintenance problems due to raveling and mini-failures at the slope face, for properly designed reinforced embankments. Brief case histories of slopes constructed using fiber-reinforced soil, and design examples using high-strength geotextile - fibers composite are discussed. [...] Planar geosynthetics such as high-strength geotextiles and geogrids have been in widespread use as earth slope reinforcement for more than a decade. The use of these materials in slope applications has been highly successful. Common practice has been to provide primary reinforcement in discrete layers throughout the reinforced zone, with shorter, intermittent layers of the planar reinforcement placed between the primary layers at the slope face to act as secondary reinforcement. The primary

When building a reinforced slope, we will primarily depend on a secondary reinforcement with a light to moderate geosynthetic fabric or grid in tight vertical spacing with relatively short embedment lengths (how far horizontally into the slope these extend). These layers will provide superficial stability to protect the embankment from shallow plane failure at the surface, while also giving compaction equipment a good platform in which to compact soil lifts all the way to the face of the slope. [...] A reinforced soil slope is defined as a compacted fill embankment that incorporates geosynthetic reinforcement to increase the soil shear to enhance the stability of the embankment when site conditions require an embankment with a steeper angle of repose (how steep soil can naturally be piled relative to a horizontal plane) or if the embankment is intended to carry a load considered unstable with the existing subgrade. [...] However, when slopes exceed 45 degrees in relativity to a horizontal plane, it’s often best to use wire forms that are either lined with geosynthetic or high performance rolled erosion control product that can retain fine soils while establishing vegetation through the facia treatment. Wire forms do not offer structural strength and should not be considered a structural element. They are placed only to keep the embankment at the desired batter (slope angle) during construction, and to assist
