Performance of Unbound Layers of a Flexible Pavement System During Aircraft Loading

The objective is to study the compaction characteristics of various aggregate materials used for construction of a flexible pavement system using a combination of laboratory tests and field data available from the National Airport Pavement Test Facility (NAPTF). The laboratory test will be conducted using the Superpave Gyratory Compactor (SGC), which can simulate trafficking conditions. The efficacy of using the SGC as a better tool to predict the performance of these aggregate materials during trafficking will also be confirmed. In addition, the performance degradation of the material due to crushing will also be studied and correlated with performance measures that the Federal Aviation Administration (FAA) uses for quality control of aggregate to study at what level of trafficking the aggregate does not meet quality control standards including shape, angularity, and grain size distribution. In addition, a micro-mechanical framework for characterizing the material behavior of the aggregate will be investigated. The study will contribute to a significant improvement in the design methodology used for design of airport pavements and provide a better understanding of the performance of pavement systems especially due to heavy aircraft loads with complex gear configuration.
