Is asphalt cement primarily made from bituminous coal tar or from petroleum byproduct?
True asphalt cement is made ONLY of petroleum byproduct, and may have varying levels of volatiles still present, but should never include any coal tar, as that is an entirely different binder. The two do have many similarities, though, particularly that they are both thermoplastic binders. But the main answer is that asphalt DOES NOT contain bituminous coal tar.
Does asphalt have glass in it?
It's not supposed to. Asphalt is a petroleum derivative (the stuff left after all the volatiles are removed), and there may or may not be rocks (crushed stone) added.
What are roads made from?
asphalt
What are some of the ingredients used by an asphalt plant to make asphalt?
Asphalt basically consists of 2 types of components: various kinds of aggregates in different size distributions providing the load bearing performance and bitumen as the binder assuring mechanical and thermal flexibility.
What is petroleum used for?
It is used mainly for fuel (airplanes, trains, automobiles), as a source of heat for homes and businesses, and in the manufacture of plastics and pharmaceutical supplies, and tar for asphalt.
