Since 1985, Kentucky has used prefabricated edge drains on many of its major highways. Three brands have been installed to date (Hydraway, Advanedge, Akwadrain). By far, the largest quantity of material used has been Hydraway. In the past year, considerable effort has been expended in observing these materials and their behavior in the field. Problems have developed with the Hydraway material, some of which were documented in Research Report No. UKTRP-88-15 (Evaluation of Hydraway Edge Drain on Pennyrile Parkway). This brief report documents the history of edge drain installations, recent observations made on the Mountain Parkway in Powell County, and makes some recommendations based upon experience gained to date.
