Evaluation of In-Place Asphalt Recycling For Airfield Applications
Over the last few decades, in-place recycling of asphalt pavements has seen increased use by the highway industry, primarily to take a advantage of potential cost and logistical savings compared to conventional reconstruction. More recently, the U.S. Navy and Federal Aviation Administration have allowed recycling to be used on airfields with lighter traffic. This report contains a discussion of in-place recycling design considerations obtained from a literature review of its use in the highway industry. Observations developed from a review of airfield pavement projects that have utilized recycling is also included. A structural analysis was performed using the Pavement-Transportation Computer Assisted Structural Engineering (PCASE) tool to determine typical stiffness values that recycled layers must achieve to support various types of military aircraft traffic for different pavement structures. Overall, in-place recycling is recommended for consideration as a rehabilitation technique for military airfield pavements, and further investigation is recommended before it is implemented it into design guidance.
