Abstract: Model-to-prototype similitude requirements were developed in this study for unsurfaced, landing-mat-surfaced, and conventional flexible and rigid pavement structures for airfields. An extensive literature search of model studies was first conducted. The general concept of dimensional analysis in the area of pavement systems was then introduced, followed by identification of important variables, development of pi terms, and formulation of similitude requirements for true and distorted models. A compensated model that distorts one or more design conditions in such a manner that the distortion is compensated is proposed for pavement systems. Other uses of model facilities are also discussed herein. A short analysis is made in the estimation of the desired size of the model and the required power of the motor for various gear configurations, loads, speeds, and scale ratios. It is recommended that a model be constructed for testing a single-wheel assembly traveling at low speeds at this stage of study.
