What is Asphalt Aggregate? (with pictures)

A hot mix asphalt (HMA), which is typically used for roads and parking lots, is as much as 95 percent asphalt aggregate by weight. The majority of aggregate in the mix is usually coarse, or large in size, followed by crushed stone and gravel. The remaining aggregate is composed of fillers, such as sand.
