Dynamic Characteristics of Coarse Aggregates within Epoxy ...

Results demonstrate that the compactness increment mainly depends on the movement and rotation of aggregates in the early stage, and rotation of aggregates in the later stage. The existence of gyration angle and the internal structure of epoxy asphalt mixture can affect the dynamic behavior of aggregates.
