Guidelines for the determination of the long-term strength of geosynthetics for soil reinforcement
This Technical Report provides guidelines for the determination of the long-term strength of geosynthetics for soil reinforcement.
This Technical Report describes a method of deriving reduction factors for geosynthetic soil-reinforcement materials to account for creep and creep rupture, installation damage and weathering, and chemical and biological degradation. It is intended to provide a link between the test data and the codes for construction with reinforced soil.
The geosynthetics covered in this Technical Report include those whose primary purpose is reinforcement, such as geogrids, woven geotextiles and strips, where the reinforcing component is made from polyester (polyethylene terephthalate), polypropylene, high density polyethylene, polyvinyl alcohol, aramids and polyamides 6 and 6,6.
This Technical Report does not cover:
Any prediction is not a complete assurance of durability.
