Evaluation of Edge Drains on Interstate 64 Fayette, Scott, and Woodford Counties

This report documents findings of the investigation of edge drains and their associated outlets on Interstate 64 from Milepost 65 to Milepost 75.6 in Fayette, Scott, and Woodford Counties. The study was initiated due to significant amounts of water and fines coming up through the AC surface. State and Federal Officials were concerned that possible failures in the edge drains were causing pumping and staining which will ultimately lead to premature pavement failure. Several factors appear to be contributing to the staining and pumping at the surface. These factors are discussed in the report
