Optimized Aggregate Gradation and Performance-Engineered Mixtures for Airfield Concrete Pavement

The proposed study is to incorporate the latest concepts of optimized aggregate gradation and Performance Engineered Mixtures (PEM) that have been successfully used in highway pavement to improve airfield concrete pavement design procedures. The goal of the study is to maintain desirable engineering performance and produce long-lasting airfield concrete pavement while promoting contractor innovation in the mix design process. The study is to be composed of a systematic theoretical and experimental analysis of aggregate gradation and particle packing to determine the most appropriate aggregate gradation optimization approach for different airfield pavements. Proper fresh and hardened concrete performance evaluation methods for airfield concrete pavement will also be developed or identified inspired by PEM concepts adopted by the highway pavement industry.
