Corrosion/Degradation of Soil Reinforcements for Mechanically Stabilized EarthWalls and Reinforced Soil Slopes

摘要

This manual is intended to provide criteria for evaluating corrosion losses whenusing coated or uncoated steel reinforcements, and for determining aging and installation damage losses when using geosynthetic reinforcements. It is intended for use in the FHWA Demonstration Project 82, Mechanically Stabilized Earth Walls and Reinforced Soil Slopes. Monitoring methods for in situ corrosion rates for steel reinforcements are evaluated and remote methods using electrochemical methods are recommended. Monitoring methods for determinations of in situ aging of geosynthetics are evaluated and protocols for implementation are recommended.
