Useful life - Pavements References from ICAO/ FAA FAA Airport Compliance Manual – Order 5190.B - 2009 (1) Grant agreements for development other than land purchase. Pavement and other facilities built to FAA standards are designed to last at least 20 years…. (PDF Page 35 – Page – 2-13)
U.S. Department of Transportation Federal Aviation Administration – AC No. 150/5320-6E Pavements designed and constructed in accordance with FAA standards are intended to provide a minimum structural life of 20 years that is free of major maintenance if no major changes in forecast traffic are encountered. Rehabilitation of surface grades and renewal of skid-resistant properties may be needed before 20 years because of destructive climatic effects and the deteriorating effects of normal usage. Structural Design. The structural design of airport pavements consists of determining both the overall pavement thickness and the thickness of the component parts of the pavement. There are a number of factors that influence the thickness of pavement required to provide satisfactory service. These include the magnitude and character of the airplane loads to be supported, the volume of traffic, the concentration of traffic in certain areas, and the strength of the subgrade soil and quality of materials that make up the pavement structure.
