Performance of Geotextile Separators-Phase 1
The research involved field investigations and laboratory testing to evaluate the properties and overall performance of geotextiles from eight different locations in eastern and central Washington. Both nonwoven and woven geotextiles were exhumed from the roadways at the eight locations, and samples of the geotextile were brought to the laboratory for index strength and permittivity testing. Samples of the basecourse and subgrade soils were analyzed for grain-size distribution. The results of the investigations and testing indicated that all of the geotextiles performed the separation function adequately, although three of them were not installed directly against the subgrade soil as intended. Damage to the geotextiles varied considerably with the type of material and the installation conditions; however, this damage was not shown to have affected the performance of the separator.
