Field Control and Performance of Asphalt Mixtures Containing Greater than 25 Percent Reclaimed Asphalt Pavement

This research study consisted of two primary objectives. The first objective was to identify an alternative method and criteria for evaluating the stiffness of the effective binder from plant produced high reclaimed asphalt pavement (RAP)-warm mix asphalt (WMA) mixtures. The alternative method was to be suitable for quality control and assurance of asphalt mixtures with high RAP contents. The second objective was to monitor the field performance of selected high RAP-WMA mixtures produced under the specification for a period of five years to determine if the pavements were durable. The research team proposed several tasks to achieve these objectives, which had to be modified due to numerous challenges that delayed the expected outcomes.
