Note: Asphalt is produced from high temperature vacuum distillation of crude oil. Composition varies depending on
source of crude and specifications of final product. It can contain trace amounts of sulfur, nitrogen and
oxygen compounds as well as trace amounts of heavy metals. Different asphalt grades may contain an anti-
striping additive.
Asphalt products can contain hydrogen sulfide, because it is naturally occurring in crude oil from which
asphalt is derived. Hydrogen sulfide can also be present as a by-product of asphalt processing.
