Sitka Airport IC ProjectLessons-Learn By Amanda Gilliland Knik Construction Presented By Dr. George Chang Transtec Group
Sitka-Rocky Gutierrez Airport Runway OverlayAlaska, May 2013
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
Hamm HCQ System HCQ GPS Navigator GPS Receiver Temperature Sensors Control Panel Accelerometer
Hamm IC Roller Operation • Front drum vibratory • Rear drum oscillatory • Two amplitude settings • Two frequency settings
IC Training • QC Manager • Setup, software/ analysis (data management), trouble shooting • Roller Operator • Use on-board display, setup • Owner Representatives • Basic training
On HAMM HCQ Software • Limitations • Passes are not viewed individually • Limited analysis • Base maps are time consuming to import
Veda Recap • Base maps • View individual passes • View roller settings • Extensive analysis
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
