ONTARIO RIDES ON US - Ontario Asphalt Pavement Council ...

The analysis for asphalt pavements is complicated by the fact that the cementing material, the asphalt cement or bitumen, has high carbon content. The average carbon content of asphalt cement is about 82 percent, and asphalt cement makes up about 5 percent of an asphalt pavement, with the rest being aggregates — stone, sand, and gravel.
