Abstract:The objectives of this research included: • Determine in-situ load-induced and temperature-related pavement responses, investigate pavement failure mechanism and structural performance, and quantify the equivalent axle load fatigue damages on RCC pavements under accelerated pavement testing; • Conduct laboratory beam fatigue tests using in-situ saw-cutting RCC slab specimens and develop a new fatigue damage model for the use of thickness design and performance evaluation of RCC pavements; and • Propose a mechanistic-empirical pavement design procedure for the thickness design of new RCC pavements.
