“…Although there are many features affecting pavement performance, typical airfield rigid pavement design processes in FAARFIELD use a trial-and-error approach to find optimum slab size (joint spacing), joint stiffness, temperature-induced initial curling, and predefined load location, using a trial-and -error approach. Since it is also not practical to determine the optimum design solution from an exhaustive set of all acceptable designs using this approach (Gaurav et al, 2011), some practical alternatives are needed to expand the airfield rigid pavement design beyond the current restricted approach, making design calculation computationally-tractable, agile, and comprehensive. To achieve this goal, this study proposes a novel approach utilizing Artificial Neural Networks (ANN) along with an optimization technique for airfield rigid pavement design, recognizing that there have been previous studies utilizing predictive models (e.g., ANN) or optimization methods in pavement design and rehabilitation problems to make pavement engineering practices versatile and practical.…”
