PAVEMENT MAINTENANCE Long-Life Airport Pavements Set a Standard for AUTHOR Kristin Dispenza Sustainable Infrastructure Resilient infrastructure reduces future maintenance costs and societal costs. CONSIDERATIONS OF sustainability and resilience are coming to dominate conversations around transportation infrastructure, especially as an increase in federal funding brings new opportunities to the industry. For airports, the FAA has been committed for more than a decade to achieving sustainability and cost goals through life cycle planning. As part of its Extended Airport Pavement Life program, the administration intends to double the expected life of runways at large hub airports, going from 20 years to 40 years. The program funds research to determine and implement optimal pavement design, construction, maintenance and rehabilitation methods. During early phases of the extended pavement life program, data was collected on pavement performance with a goal of identifying factors that would extend service life. Testing was performed using pavement condition index (PCI) assessments, conducted in accordance with ASTM D5340. A 2014 FAA report, " Performance Trends 18 \ AIRPORT BUSINESS / NOVEMBER/DECEMBER 2022
