Voids filled with asphalt are spaces within the VMA that contain liquid binder.

• A. True.
• B. False.
• C. They contain air.
• D. They contain aggregate.

Answer: (A)

Voids in the mineral aggregate (VMA) are all the empty spaces in the compacted aggregate structure, including the spaces between particles as well as internal voids within the aggregate. After compaction, some of these spaces will be filled with asphalt binder, while others remain as air voids. The term “voids filled with asphalt” describes the portion of VMA that the liquid binder will occupy. This is why the statement is true: those binder-filled voids are indeed spaces within the VMA that contain liquid binder. In practice, this concept relates to the idea of voids filled with asphalt (VFA), which is the percentage of VMA occupied by binder.
