LABORATORY EVALUATION OF PREFABRICATED HIGHWAY EDGE DRAINS. FINAL REPORT

This study evaluated prefabricated highway edge drains to improve the existing practice and to set guidelines for their proper selection. Two primary evaluations received attention: the first was the effect of installation and in-service loading on the hydraulic and strength capacities of a prefabricated highway edge drain; and the second was the performance of the geotextile filter. A limited field evaluation of prefabricated highway drains indicated structural failure of the core and an inefficient geotextile. Based on the field study, laboratory testing and theoretical modeling, guidelines were given for the strength and hydraulic requirements of the drain. A retention criterion was given for the geotextile filter. The criterion was based on reliability theory and accounted for the overall pore size distribution, porosity and thickness of the geotextile. Field geotextile samples were evaluated for their long term performance using image analysis. The evaluation indicated only partial clogging of geotextiles in service for 4 to 7 years.
