In today's world, pavement engineers are faced with the demand of designing and building durable and cost-effective, yet environmentally friendly pavement systems. ""Airfield and Highway Pavements: Efficient Pavements Supporting Transportation's Future"" explores the newest advances and challenges in pavement design and construction. This proceedings contains 57 peer-reviewed papers presented at the 2008 Airfield and Highway Pavements Conference in Bellevue, Washington, October 15-18, 2008. Topics addressed in the proceedings include: pavement modeling; characterization of pavement materials; pavement management, evaluation, and rehabilitation; performance of stabilized and unbound pavement layers; pavement design and analysis; and pavement performance studies. This proceedings consists of papers from both practitioners and academics and will be invaluable to anyone involved with pavement engineering and construction.
