test. Slope stability analyses should account for interface shear strength along a geocomposite drain. The geocomposite/soil interface will most likely have a friction value that is lower than that of the soil. Thus, a potential failure surface may be induced along the interface. Geotextile reinforcements (primary and intermediate layers) must be more permeable than the reinforced fill material to prevent a hydraulic build up above the geotextile layers during precipitation. Special emphasis on [...] or uniaxial) and geotextiles. These reinforcements are a wrapped face consisting of a layer of geogrid that wraps around the face and a layer of geotextile to prevent erosion of the reinforced soil materials.

recommended the use of geogrid or a combination of geogrid and geotextile for slope reinforcement, while the others recommended independent use of geotextile. Some prefer high strength geotextiles over geogrids, as they provide a separation function and can be more cost effective in certain cases. Figure 2. Recommended Design Methods. The internal stability of a soil slope can be determined by four basic factors, including the slope angle (β), soil weight (W), cohesion (c), and internal [...] design guidelines for GRSS. The existing topography, subsurface conditions, and soil properties must be considered when evaluating the site for construction. The investigation should include determining the availability of the required type of reinforced fill and backfill materials. 3. Geogrid or geotextile constructed of polyester, polypropylene, or polyethylene are recommended for soil slope reinforcement. The material should be resistant to heat, ultraviolet light, attack by bacteria and [...] overall slope stability were 40 ft for the bottom three geogrid layers and 30 ft at the top of the slope. The slope face was constructed using prefabricated welded wire forms bents to the specified slope batter of 45°. A secondary reinforcement and a seven ounce non-woven geotextile were place in each wire form prior to primary geogrid placement and compacted soil. The secondary reinforcement provided surficial slope stability and a minimum 6 ft top and bottom embedment specified by

it was shown that the use of horizontally placed geosynthetic reinforcement to stabilize surficial soils in slope applications is a commonplace procedure. For steep reinforced slopes, for example, relatively short secondary reinforcement layers are placed between the primary reinforcement to provided stability to the surface soil during and after construction to help with the growth of vegetation.

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 [...] The primary reinforcement provides overall stability, while the intended purpose of the secondary reinforcement is to reduce raveling and minifailures of the slope face between the primary reinforcement layers. However, in many cases the secondary reinforcement does not effectively reduce the raveling and mini-failures long term. This has resulted in significantly increased maintenance costs on many projects. Until recently, no viable solution for this problem was available. Within the past

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 [...] In situations where reinforced slopes are subjected to severe erosive forces associated with water currents and wave attack, the erosion protection system must be specifically designed to resist these forces. Typically, such severe cases will require a ‘hard’ armor erosion protection system such as riprap, gabions, articulating concrete blocks, or fabric-formed concrete. While these systems do not incorporate a geosynthetic face wrap, a geotextile filter is typically installed beneath the [...] ### Design principles of reinforced soil slopes
The design of reinforced soil slopes hinges on two critical components: the facing system and the reinforcement strategy. The facing system is integral to erosion protection and structural support, enabling the formation of slopes that surpass natural stable inclinations without compromising stability. Secondary reinforcement, typically comprising geosynthetic materials, aids in compaction and mitigates surficial sloughing at the slope face.

Ecological approaches, including vegetation planting (Feng et al., 2025; Li et al., 2016b; Löbmann et al., 2020; Zhu et al., 2017), geotextile application (Li et al. 2020a, 2025; Palmeira and Tatto, 2015), and soil bioengineering (Bordoloi and Ng, 2020; Romano et al., 2016; Stokes et al., 2010), enhance slope stability through root reinforcement and surface protection, while promoting biodiversity and microclimate regulation. For example, geotextile-armor layer composites can mitigate erosion [...] Two innovative geotextile-based slope stabilization and erosion control approaches were developed in this study, including vegetation-geotextile composites and geotextiles treated with alkali-activated binder (AAB). Experimental investigations were conducted to evaluate the effectiveness of different slope protection measures in delaying runoff onset, lowering erosion rates, and improving slope stability under varied rainfall intensities and slope gradients. It was found that bare slopes [...] slope. Furthermore, AAB-treated geotextiles delivered the highest erosion resistance, while vegetation-geotextile composites provided significant ecological benefits in terms of soil temperature regulation and organic matter release. As a result, integration of AAB treatment with vegetation-geotextile systems can serve as a long-term slope stabilization solution that simultaneously addresses engineering requirements and environmental objectives under climate change scenarios.

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 [...] GRE with all slope inclinations. The geosynthetic reinforcement is extended to wrap the face with sufficient embedment length, typically at least 4 feet. Include a layer of non-woven geotextile behind the geosynthetic reinforcements to retain reinforced soil. The non-woven geotextile must have enough embedment length at both the top and bottom of the wrap. Geosynthetic Reinforced Embankments September 2023 Page 10 of 17 Figure 4: GRE Wrap Face Detail Erosion control blanket or mat is generally [...] System Water that infiltrates through deteriorated pavement or the retained slope may compromise the stability of the GRE. To drain water in the soils, provide a drainage system between the reinforced soil and the retained soil (Figure 1) especially when design for highway widening or slope restoration. A typical drainage system for GRE includes: • • • Subdrain placed behind and near the bottom of the reinforced soil and along the alignment of the GRE. The subdrain includes 4-inch diameter
