Summary *

As requested, the site was visited by our AS Engineering and Consulting (ASEC) representative for the purpose of providing quality control inspection and testing services. Visual observation techniques were employed to verify compliance with project drawing/specifications, applicable codes, and materials
submittals. The following observations were observed on site this day.

Our ASEC representative was on site for the observation/testing of the placement of fill/backfill. Our representative met with Brad (superintendent) to discuss density testing performed on recycled concrete mix being used as GAB on the runway. It appears to be compacted, but test results show 95% compaction or less (on the NOVA (QA) proctor) and even less on the ASEC proctor. Our representative reported the failing tests to Brad, and the decision was made to continue forward with the paving of the runway. Brad made it clear that as long as the test results were consistent, and not continuing to rise in compaction rate, then they were fine with the results. It was made clear that the mix of recycled concrete could be constantly changing. So observational techniques were used alongside of density testing to evaluate compaction.

Our ASEC representative recommended a proof-roll be conducted with a loaded tandem dump truck to check for pumping and/or rutting. This recommendation was declined by Brad and the PDK representative that was present on site. They said the airport does not require a proof-roll on the GAB base, so one will not be performed. This information was passed along to an ASEC supervisor. CWM informed our ASEC representative that as long as compaction testing was consistent (even if failing) then they were going to proceed with the tasks at hand.

We appreciate the opportunity to be of service to you on this project. If you have any questions regarding this report, please feel free to contact us. We will be more than happy to discuss it with you.
