which would help reduce the geogrid lengths and the subsequent excavation width required while still supporting the high surcharge loads from crane operation during construction. Internal and external stability analyses indicated that a uniaxial geogrid product, placed at 1.5-foot (0.5-m) vertical intervals at lengths equal to 90% of the RSS height, was required. At the RSS face, a relatively high-tenacity polypropylene multifilament woven geotextile was used as a wrap to retain the granular material. The geotextile was placed inside of a 1.5-foot (0.5-m) tall galvanized welded wire basket that was used to help form the facing. Each basket was placed at a 1-inch (2.5-cm) horizontal offset to keep the RSS tolerance within the 5-foot (1.5m) maximum void span length at the top of the RSS. A typical RSS section is shown in Figure 2, while the RSS facing is shown in Figure 3. RSS design and construction challenges There were some unique design and construction challenges associated with the RSS. A portion of the RSS had to be constructed to align with a descending chevron concrete structure that was supported on grade beams on H-piles. The RSS had to turn multiple 90˚ outside corners and ascend at a specific angle to be able to Flexible, high-strength, temperature-resistant grid for effective reinforcement of asphalt layers.
