The Impact of the RAP Cluster Dissociation on Gradation and Shape Properties of Aggregates from Recycled Asphalt Mixtures

The presence of clusters in reclaimed asphalt pavement (RAP) is a critical point that affects the RAP homogeneity. In this phenomenon, different RAP particles are working together as a single aggregate. The cluster dissociation occurs during hot asphalt mixture production and compaction in the field. This research is concerned with the impact of the cluster disintegration on the recycled asphalt mixture aggregate properties. Stages of binder...
