Evaluation Of Pavement Edge Drains And Headwalls On I-264 (Watterson Expressway) Jefferson County, L. John Fleckenstein, Brad W. Rister, David L. Allen
Kentucky Transportation Center Research Report
This report documents the findings from the investigation of pavement edge drains and headwall conditions on six Watterson Expressway Projects in Jefferson County. These projects include the Newburg Road Interchange, Bardstown Road Interchange, Taylorsville Road Interchange, Breckinridge Road Interchange, l-64 1nterchange, and Shelbyville Road Interchange. The study was initiated due to an on-site inspection by Federal Highway Administration, Kentucky Transportation Center, and District 5 personnel who indicated several of the outlet pipes were clogged or collapsed. It was suggested by Federal Highway Administration personnel that a mini pipeline inspection camera be used to verify the conditions of the outlet pipes …

Performance And Cost Effectiveness Of Pavement Edge Drains, L. John Fleckenstein, David L. Allen
Kentucky Transportation Center Research Report
It is apparent from research conducted under this study that edge drains increase subgrade strength through the removal of water. It is also apparent in most cases that the edge drains increase pavement life by approximately seven years. Current cost benefit analysis indicates that edge drains can provide a cost savings of approximately $200,000 dollars a mile over the life of the pavement. Research also indicates that if edge drains are not properly installed and maintained they can doe more damage then good. It is evident that edge drains should be inspected with a pipeline camera prior to final acceptance …
