Hot Asphalt Oil

• Hot Asphalt Oil (Bitumen/Asphalt Cement) is the primary binder in road construction.

• It is a dense, viscous byproduct of petroleum refining.

• Its main purpose is to bind aggregates (crushed stone, sand) to form durable pavement.

• For use, it must be heated to 250-350°F (120-175°C) to become liquid.

• This heat allows it to fully coat aggregates, creating Hot Mix Asphalt (HMA).

• Key properties: exceptional durability, flexibility, and strong adhesion to materials.

• It is naturally waterproof, protecting the road from moisture damage.

• Asphalt is a highly sustainable material; it can be recycled into new pavement.

• Handling requires strict safety protocols due to extreme temperatures (e.g., heat-resistant PPE).



• Ultimately, it is the fundamental component for building and maintaining modern road infrastructure.
