Use of Filter Fabric for Sub-grade Drainage Systems for Highways
This report describes the installation of subgrade drains using various types of filter fabrics. Results on testing before, during and after a two year period are included along with conclusions and recommendations. The system was constructed in 1976 on a highway previously built without subgrade drains. Monthly samples were lifted for water quality testing. Instrumentation was installed for moisture-temperature observations. The subgrade drains were excavated and each material retested after being in service for a one and two year period. The drains are still functioning efficiently; however, test results indicate additional monitoring needs to be done before a conclusion can be stated on longer service life.
