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 [...] 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 [...] at Castleberry Engineer: Soil Reinforcement Design Contractor: ECM Purpose: Maximize Available Land Geosynthetic Material: Reinforcement: Geocomposite Facing: Polypropylene Mesh Slope Height: 30 ft Slope Face: 71,000 ft2 Construction Sequence: The base was a well compacted subgrade and geosynthetics were installed as primary reinforcement.

### 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. [...] 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

by Zonberg et al. (1998) and Tiwari and Samadhiya (2016) for reinforced slopes, a parametric study was carried out on the 40°, 50°, and 60° slopes (unreinforced and reinforced) as presented in Figure 2 (a-d) by varying the slope soil strength parameters (c’ from 0 to 5 kPa and ϕ’ from 30° to 50°), while keeping the slope height, geosynthetic layout and soil unit weight constant, to determine their effect on the factor of safety, F. The range of c’ and ϕ’ adopted in the study are typical of [...] may involve a low-height steep slope that may not need a stone wall support as shown in Figure 1. In such cases, the slopes can be reinforced with geosynthetic layers (geotextile or geogrid), to improve the stability, defined in terms of factor of safety F to an acceptable value. Geosynthetic layers have proven to be effective and economical in improving the mechanical properties of soils, and moreover, they allow to construct environmentally friendly and sustainable structures (Shukla et al. [...] slope: rotational and translational. The investigation also produced design charts which show a relationship between the soil properties, slope geometry and factor of safety. Jewell (1991) improved the existing reinforced slope design charts produced by Jewell et al. (1984) to use less reinforcement material but maintained the same level of safety. The new design charts replaced the existing ones and can be used to analyse reinforced slopes with angles ranging from 30° to 90°. Mandal and Joshi

For these types of projects we have developed a system for building green walls or slopes—geotextile-reinforced soil slopes that have a uniform covering of vegetation on their facade to give a natural appearance. The resulting slope is attractive and as strong and robust as traditional solutions that use concrete, block, or stone facades. [...] ## 3. Design for a ‘green’ reinforced soil wall or slope
A case history to describe the process of design for a geosynthetic-reinforced soil retaining wall or slope was designed and constructed in Costa Rica in January 2008. This slope was designed to have an erosion resistant facade of vegetation and for this it is referred to as a “green” reinforced soil slope.
### 3.1 Initial conditions [...] Geosynthetic-reinforced soil walls or slopes are also attractive solutions because of the flexibility they provide, as their design can be adapted to suit a range of different loads, solicitations, geometries, landscape features, and environments. Increasingly urban housing complexes and new tourist developments are emphasizing ecological awareness and care for the environment in their construction, and geosynthetic-reinforced soil walls are used because they meet the construction goals.

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 [...] 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

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. Inextensible reinforcements consist of bars or bar mats (metallic grids) and shall meet the requirements in STS SC-M-713 (latest version) for Geotechnical Design Manual APPENDIX D January 2022 D-25 Mechanically Stabilized Earth (MSE) Walls for the inextensible material properties.

In addition, the plans should also include a requirement for the Contractor to provide the results of testing of the mechanical connection. When geotextiles are used as the extensible reinforcement, the geotextile shall be placed so that the strong axis is perpendicular to the face of the RSS. The geotextile reinforcement materials to be used to construct an RSS shall meet the criteria provided in STS SC-M-203-3 (latest version) for [...] 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.
