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.

On Monday, April 6 at 8:00 AM, paving operations began at the Calhoun Tommy David Airport project. The placement started approximately 30 minutes later. As trucks began arriving, the first five temperature readings were recorded, ranging between 280°F and 320°F.

Asphalt placement commenced at Station 33+50 with an asphalt cement (AC) content of 5.82%, a mix ID of 12.5 MM RAP, and a target density of 156.9 pcf. The average in-place density achieved was approximately 97%. Paving continued from Station 33+50 through Station 36+50 to 38+50, extending toward the taxiway and apron widening area.

Nuclear gauge density testing was performed on both sides of the pavement, with a total of 15 readings taken across the section. These results were compared and verified with both the CWM QC and UES representatives.

Following density testing, the CWQC technician selected locations with the highest densities and extracted core samples. These cores were measured, labeled, and sent to the laboratory to determine maximum density and asphalt content. Based on laboratory analysis, an offset of +4.8 was calculated and applied. After applying the correction factor, all density results met specification requirements.

Work then progressed to the taxiway area opposite the terminal, where additional random density checks were performed. All test results in this area were within acceptable limits, and the paving operations were deemed compliant with project specifications.

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.
