There are two basic ingredients in asphalt. The first are aggregates; this is a mix of crushed stone, gravel, and sand.
Aggregates make up about 95% of hot mix asphalt pavement. The other 5% is bitumen. Bitumen is the black or dark viscous material that holds the aggregates together, and is composed of polycyclic hydrocarbons, which is a petroleum byproduct.
