Bitumen 40/50

Definition of Bitumen Penetration Grade 40/50 – Iran Bitumen Supply │ IBITMCO

Bitumen Penetration Grade 40/50 is a semi‑hard paving‑grade bitumen with a penetration value between 40 and 50 under standard test conditions. This grade is widely used in road construction, hot mix asphalt (HMA) production, and high‑performance pavement applications. At Iran Bitumen Supply │ IBITMCO, our Bitumen 40/50 is produced through the controlled air‑blowing (oxidation) of high‑quality vacuum bottom—the residue left from the vacuum distillation of crude oil in refineries. Penetration grade bitumen is classified based on penetration value and softening point, with the designation determined solely by the penetration range. Bitumen 40/50 exhibits thermoplastic behavior, softening at high temperatures and hardening at lower temperatures. This temperature‑viscosity relationship is essential for evaluating performance characteristics such as adhesion, rheology, durability, and application temperature. The stiffness and temperature sensitivity of Bitumen 40/50 depend on the crude oil source and refining method. As a semi‑hard penetration grade, it is ideal for tropical climates, high‑temperature regions, and heavy‑traffic roadways. Bitumen 40/50 is one of the most commonly used grades globally and serves as a base material for many other bituminous products.

HS Code of Bitumen 40/50

Bitumen Penetration Grade 40/50 is typically classified under HS Code 27132000, which covers petroleum bitumen and other residues from petroleum oils. This standardized international code ensures uniformity in global trade, customs documentation, and product identification.

Applications of Bitumen Penetration Grade 40/50

Bitumen 40/50 supplied by Iran Bitumen Supply │ IBITMCO is suitable for Road construction and highway surfacing, Hot mix asphalt (HMA) for base and wearing courses, Pavements in tropical and warm climates, Heavy‑duty roads exposed to high traffic loads, Asphalt repair and maintenance projects. Due to its high air‑blowing stability and resistance to softening, Bitumen 40/50 performs exceptionally well in hot regions, maintaining its structural integrity even under elevated temperatures.
