  1. Sitka Airport IC ProjectLessons-Learn By Amanda Gilliland Knik Construction Presented By Dr. George Chang Transtec Group

  2. Sitka-Rocky Gutierrez Airport Runway OverlayAlaska, May 2013

  3. IC Specification • Provide one IC roller per paver • Provide on-site training for contractor and agency • Provide manufacturer representative for IC support • IC test section • Provide Veda files to agency • Operations Criteria • 95% meet optimum passes • 70% meet target ICMV values (HMV) • 10% deduction from item 401 when IC is not functioning properly

  4. Night Paving

  5. Hamm HCQ System HCQ GPS Navigator GPS Receiver Temperature Sensors Control Panel Accelerometer

  6. Hamm IC Roller Operation • Front drum vibratory • Rear drum oscillatory • Two amplitude settings • Two frequency settings

  7. IC Training • QC Manager • Setup, software/ analysis (data management), trouble shooting • Roller Operator • Use on-board display, setup • Owner Representatives • Basic training

  8. Hamm HCQ Software

  9. On HAMM HCQ Software • Limitations • Passes are not viewed individually • Limited analysis • Base maps are time consuming to import

  10. Veda Software

  11. Veda Temperature Map

  12. Veda Analysis

  13. Veda Point Tests

  14. Veda HMV Map

  15. Veda Software HMV Comparison

  16. Veda Software vs. Thermal Camera

  17. Veda Recap • Base maps • View individual passes • View roller settings • Extensive analysis

  18. Strengths and Limitations • Strength • Real time data useful – particularly for night paving • Records everything for troubleshooting (if required) • Helps with density consistency • Verifies 100% coverage • Limitation • Does not predict density – ICMV and density do not correlate at this project • Room for error in data analysis

  19. Thank You !
