Climate Change Impacts to Arctic Airfields
This open-ended research investigates the correlation between climate history, climate change, and pavement infrastructure performance for specific airfields in Arctic and Subarctic Alaska. Parameters such as temperature, air indices, and permafrost extent are compared to PAVER pavement management system data and construction costs for four locations. Site criteria are developed and implemented to select airfields for analysis that provide representative conditions. Climate data are analyzed to show the range of variability and temporal trends. Geotechnical borehole data are consolidated to portray nominal local permafrost extent. Data trends show that the depth of upper extent of permafrost at locations is increasing with time. PAVER family curves compare degradation rates and airfield pavements in areas with permafrost were shown to degrade two–three times faster compared to locations absent of permafrost. Regression of Pavement Condition Index (PCI) degradation rate and permafrost upper extent showed correlation. Construction cost histories from the Federal Aviation Administration Airport Improvement Program are included in trend analyses. Cost estimates for typical maintenance treatments are generated and applied to pavement inspections to model maintenance requirements and predict changes in airfield rehabilitation frequency.
