Personnel from the Kentucky Transportation Center performed a visual inspection of newly constructed ramp pavement at the Bluegrass Airport in Lexington, Kentucky. The inspection was conducted in May, 1996 at the request of airport engineers. The inspection revealed a number of concrete apron slabs that had cracked. Attempts had been made (apparently by the contractor) to seal the cracks by epoxy injection. The visual inspection indicated that the epoxy may not have been performing as hoped, and that some of the cracks did not appear to be sealed. As a result, it was decided to obtain cores of the cracked slabs in the area of the cracks in an attempt to determine if the epoxy was performing as it should have been.

During the inspection, other concrete damage was noted along and associated with two drainage trenches constructed as a part of the new ramp. This damage will be described in detail later in this report.
