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

Sitka-Rocky Gutierrez Airport Runway Overlay Alaska, 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

Night Paving

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

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

Hamm HCQ Software

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

Veda Software

Veda Temperature Map

Veda Analysis

Veda Point Tests

Veda HMV Map

Veda Software HMV Comparison Property“End”“Middle” Frequency - vpm , 3000 Amplitude - in Speed - mph Temperature – degrees F HMV Average Mat Density - % 96

Veda Software vs. Thermal Camera

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
