Field Control and Performance of Asphalt Mix Containing Greater than 25% Reclaimed Asphalt Pavement

As the Alabama Department of Transportation (ALDOT) is interested in the utilization of higher percentages of reclaimed asphalt pavement (RAP) in asphalt mixtures, this research seeks to: 1) identify an alternative method and criteria for evaluating the stiffness of effective binder from plant produced high RAP-WMA mixtures and ensure that this method is suitable for quality control and assurance of mixtures with high RAP contents, and 2) monitor the field performance of selected high RAP-WMA mixtures produced under the specification for a period of 5 years to determine if the pavements are durable.
