Topic Description:

This presentation will be focused on Reinforced Soil Slopes (RSS) Systems with vegetated facia. Due to the steep grades that can be achieved with RSS (up to 70 degrees), it can be very difficult to establish and maintain grass type vegetative cover. The steepness of the slope can limit the amount of water absorbed by the soil; and therefore, the selection of autochthonous types of plants is always recommended. Many RSS systems use a synthetic (permanent) erosion control mat to improve the performance of grass cover. The mat could be also made from natural fibers.This study will provide participants with technical details, installations tips starting from the different categories described in FHWA manuals (Publication No. FHWA-NHI-10-025 FHWA GEC 011 – Volume II) and case studies from real examples across United States, Canada and overseas.
