VMA and the air voids. Absorption of the asphalt cement into the aggregate was also taken into account in the volumetric analysis. McLeod recommended again that the lowest permissible asphalt content in a HMA mix should be % by weight, to ensure mix durability. This amounts to about 10% asphalt cement by volume.
Aggregate | Colorado Geological Survey
Aggregate. Sand, gravel and crushed stone form a group of industrial minerals known as "aggregates". These materials are necessary for concrete, road base and coverings, and construction fill. Most producers near metropolitan are relying more on crushed stone than on sand and gravel because sand and gravel are found mostly in river valleys.
