Evaluation of Geocomposite Pavement Panel Drains Installed in a Sand Backfill Under Revised Installation Specification

L. John Fleckenstein & David L. Allen
Prior to 1989, highway edge drains were backfilled with the existing trench material and dynamically compacted with a tamping shoe. The net result was damage to the inner core of the edge drain. In response to these problems the installation specification was revised in 1989 to insure the integrity of the drainage system. The revised method of installation consisted of moving the panel to the shoulder side of the trench and then flushing a sand...

Kentucky Transportation Center personnel also monitored several bridges during repainting operations. The inspections revealed that the original paint was in excellent condition....

Experimental Coating on Interstate 264 in Jefferson County

Bobby W. Meade, Sidhir Palle & Theodore Hopwood
A waterborne acrylic coating was applied over a washed and tool cleaned zinc/vinyl system as a maintenance overcoat. The coating has several positive characteristics in that it is “user friendly”, substrate tolerant, develops good adhesion quickly, and is environmentally friendly. There were some issues concerning quality of work in surface preparation and application and in the fact that on two locations bubbles developed in the newly applied coating. The cause of the bubbling has not...

Improved Bridge Expansion Joints

Sudhir Palle, Theodore Hopwood & Bobby W. Meade
The Kentucky Transportation Cabinet (KYTC) has both open and closed bridge expansion joints and associated details that are problematic.
