Bitumen VG40

Bitumen VG40 is a high-viscosity paving grade bitumen designed for demanding road construction and heavy-duty asphalt applications. It is classified according to viscosity at specified temperatures and provides higher stiffness and load-bearing performance than lower viscosity grades such as VG10, VG20, and VG30. VG40 bitumen is particularly suitable for roads exposed to heavy traffic, high axle loads, elevated temperatures, and repeated mechanical stress. Its controlled viscosity, strong adhesion, water resistance, and durable performance make it a preferred binder for infrastructure projects requiring long service life.

Bitumen VG40 offers excellent resistance to deformation, rutting, and fatigue under demanding traffic conditions. Its relatively high viscosity provides improved structural stability in asphalt mixtures while maintaining suitable workability during hot mixing and paving operations. The material can be used in asphalt concrete, dense-graded mixtures, heavy-duty pavements, industrial roads, intersections, airport pavements, container terminals, and other high-load transportation infrastructure. Proper storage, heating, handling, and mixing temperatures should be maintained according to the applicable technical standard and project requirements.

Commercially, VG40 bitumen is supplied in bulk and export-ready packaging according to buyer requirements, including new steel drums and other suitable industrial packing formats. Specifications may be supplied according to applicable ASTM, AASHTO, or equivalent national and international standards. Buyers should confirm viscosity, penetration, softening point, flash point, solubility, and other quality parameters before purchase. Bitumen VG40 is widely selected by asphalt producers, road contractors, infrastructure companies, distributors, and international trading companies looking for a reliable high-viscosity paving binder.

FAQ Bitumen VG40

Bitumen VG40 is mainly used for heavy-duty asphalt pavements, highways, intersections, industrial roads, airport pavements, and roads exposed to high traffic and heavy axle loads.

VG40 has higher viscosity and generally provides greater resistance to deformation and rutting under heavy traffic and high-temperature conditions compared with VG30.

It should be stored in suitable heated tanks or approved containers, protected from contamination and excessive moisture, with temperature control according to handling and application requirements.

VG40 can be supplied in new steel drums, bulk tankers, and other export-oriented packaging formats depending on the buyer's requirements and destination.

International buyers looking for reliable Iranian suppliers can source Bitumen VG40 through Irancorps, which can assist with supplier identification, product specifications, commercial coordination, and export sourcing.

Yes. Irancorps can support international buyers in sourcing Bitumen VG40 from Iran and coordinating commercial requirements based on the destination market, required specification, quantity, and packaging.
