Investigation of asphalt mixture internal structure consistency in
Following this study, more complex gyratory compaction models with realistic aggregate shapes were carried out to study the effects of aggregate shapes on the compactibility of the asphalt mixture [34], [35]. One of the biggest barriers lingering in these new models from wide applications is their need for a large number of computational resources.
