註釋

This report addresses four proposed revisions to the AASHTO guidelines concerning design and construction of geosynthetic-reinforced soil (GSR) walls (AASHTO, 1996). The proposed revisions are regarding: lateral earth pressure on wall facing, long-term deformation, truncated reinforcement at wall base and the CTI tails, and embedment and leveling pad. For each of the proposed revisions, the deficiencies in the current AASHTO guidelines are addressed in detail; the literature on the research findings and measured performance is presented; and the specific revision is proposed. The limitations and practical implications of each proposed revision are also discussed.
