Weathering properties of geotextiles in ocean environments

Abstract

This paper provides data on weathering properties and reduction factors for two geotextiles in ocean environments. The study included outdoor ultraviolet (UV) exposure tests performed at the Harbor and Marine Technology Research Center in Taiwan using a black polypropylene and a white polyester geotextile. Ultraviolet exposure was the most significant factor in reducing the strength properties of the geotextiles tested in an ocean environment. Seawater immersion had the least weathering effect on the engineering properties of the test geotextiles among the test conditions. The effect on engineering properties of placing samples within the tidal zone was slightly higher than that for the immersion condition. Reduction factors for UV exposure and seawater weathering for the test geotextiles are reported.
