Question 1

What is bitumen and what is it used for?

Accepted Answer

Bitumen is a dense, viscous petroleum product obtained from the distillation of crude oil. It is the principal binder in asphalt for road construction and is also used for waterproofing, roofing, industrial coatings and insulation. Its strong adhesive and cohesive properties make it ideal for holding aggregate together in flexible pavements.

Question 2

What is the difference between bitumen and asphalt?

Accepted Answer

Bitumen is the black, sticky binder; asphalt is the finished mixture of bitumen and mineral aggregates (sand, gravel, crushed stone) laid on roads. In everyday North American usage "asphalt" is sometimes used to mean the binder itself, but technically bitumen is the binder and asphalt is the composite.

Question 3

Is bitumen the same as tar or pitch?

Accepted Answer

No. Bitumen is derived from crude oil refining, whereas tar is produced by the destructive distillation of coal or wood. Although both are dark and viscous, they differ chemically and in performance. Modern road and roofing applications use bitumen, not coal tar.

Question 4

What types of bitumen does Bitumax supply?

Accepted Answer

Bitumax supplies penetration grade bitumen, viscosity grade bitumen, oxidized (blown) bitumen, cutback bitumen and polymer modified bitumen, along with bitumen emulsions on request. Each product family covers multiple grades to match paving, roofing and industrial specifications.

Question 5

What is oxidized (blown) bitumen used for?

Accepted Answer

Oxidized bitumen is produced by blowing air through hot bitumen, raising its softening point and reducing its temperature susceptibility. It is used for roofing felts, waterproofing membranes, pipe coatings, electrical and industrial applications where a harder, more heat-stable binder is required.

Question 6

What is cutback bitumen?

Accepted Answer

Cutback bitumen is bitumen diluted with a petroleum solvent (such as kerosene or naphtha) to lower its viscosity for cold application. It is classified as rapid-curing (RC), medium-curing (MC) or slow-curing (SC) depending on the solvent used, and is common for priming, tack coats and surface dressing.

Question 7

What is polymer modified bitumen (PMB)?

Accepted Answer

Polymer modified bitumen is bitumen blended with polymers such as SBS or SBR to improve elasticity, rutting resistance and durability at high and low temperatures. PMB is specified for heavy-duty highways, airports and applications demanding longer pavement life.

Question 8

What is bitumen emulsion?

Accepted Answer

A bitumen emulsion is a suspension of fine bitumen droplets in water, stabilised with an emulsifier. Emulsions are applied cold and are used for tack coats, prime coats, slurry seals and cold-mix patching. They are classified as cationic or anionic and by breaking speed (rapid, medium, slow setting).

Question 9

What do penetration grades like 60/70 and 80/100 mean?

Accepted Answer

Penetration grading measures how far a standard needle penetrates a bitumen sample (in tenths of a millimetre) at 25°C under fixed load and time. A 60/70 grade penetrates between 60 and 70 dmm; a lower range means a harder bitumen. Common grades include 40/50, 60/70, 80/100 and 85/100.

Question 10

What are VG (viscosity) grades of bitumen?

Accepted Answer

Viscosity grading (VG-10, VG-20, VG-30, VG-40) classifies bitumen by its absolute viscosity at 60°C, which correlates with in-service performance across climates. VG-30 is widely used for hot-mix paving in moderate-to-hot regions, while VG-40 suits high-stress, high-temperature applications.

Question 11

Which bitumen grade should I use for road paving?

Accepted Answer

The right grade depends on climate, traffic load and the pavement layer. Hotter climates and heavier traffic generally call for harder grades (e.g. 40/50, VG-40 or PMB), while colder climates favour softer grades (e.g. 80/100). Our technical team can recommend a grade against your project specification.

Question 12

What is the softening point of bitumen?

Accepted Answer

The softening point is the temperature at which bitumen becomes soft enough to flow, measured by the ring-and-ball method. A higher softening point indicates greater resistance to deformation at high service temperatures — important for roofing and hot-climate paving.

Question 13

What is the difference between penetration and viscosity grading?

Accepted Answer

Penetration grading classifies bitumen by needle penetration at 25°C, while viscosity grading classifies it by absolute viscosity at 60°C. Viscosity grading is considered more rational because it measures a fundamental engineering property at a temperature closer to road surface conditions.

Question 14

What standards and test certificates come with your bitumen?

Accepted Answer

Our bitumen conforms to international specifications such as ASTM, EN and AASHTO, depending on grade. Every shipment is supplied with a certificate of analysis (COA) and, where required, SGS or third-party inspection covering penetration, softening point, ductility, flash point and other key parameters.

Question 15

How do I request a bitumen price quote?

Accepted Answer

Send us your required grade, quantity, packaging and destination port, and we will return a formal quotation with current pricing, lead time and payment terms. You can start an enquiry through our contact page or the quote request form.

Question 16

What is the minimum order quantity (MOQ)?

Accepted Answer

Minimum order quantities vary by grade and packaging. Bulk shipments are typically arranged by the full container load or vessel parcel, while drummed and jumbo-bag orders can start at smaller volumes. Contact us with your target quantity and we will confirm feasibility.

Question 17

What payment terms and methods do you accept?

Accepted Answer

We commonly work with an irrevocable Letter of Credit (LC) at sight, telegraphic transfer (TT) and, for established customers, documents against payment. Payment terms are confirmed on the proforma invoice before shipment. We do not request payment to personal accounts.

Question 18

What is an Incoterm and which do you trade on?

Accepted Answer

Incoterms are internationally recognised trade terms defining the responsibilities of buyer and seller. We quote on FOB, CFR and CIF most commonly, and can arrange EXW or other terms on request. The chosen Incoterm determines who arranges and pays for freight, insurance and clearance.

Question 19

Do you provide samples before an order?

Accepted Answer

Yes. For qualifying enquiries we can provide product samples and full certificates of analysis so your laboratory can verify the grade against your specification before committing to a bulk order.

Question 20

How does the end-to-end buying process work?

Accepted Answer

The process runs from enquiry and quotation, through proforma invoice and payment terms, to production, third-party inspection, packaging, loading, shipping documents and delivery. Our buying process flow page sets out each step in detail.

Question 21

Which ports and countries do you ship bitumen to?

Accepted Answer

We export bitumen worldwide, serving markets across Africa, Asia, the Middle East, Europe and the Americas from major loading ports in the Middle East and Asia. Tell us your destination port and we will confirm routing and transit time.

Question 22

How is bulk bitumen transported?

Accepted Answer

Bulk bitumen is shipped in heated bitumen tankers or in bitutainers (heatable ISO tank containers), while packed bitumen travels in steel drums, jumbo bags or poly-bags inside standard containers. The best mode depends on volume, destination infrastructure and grade.

Question 23

What is a bitutainer?

Accepted Answer

A bitutainer is an insulated, heatable tank container that transports bulk bitumen at controlled temperature without the need for drums. It allows convenient handling, storage and discharge at the destination and is ideal where drum disposal or bulk tanker access is a constraint.

Question 24

What shipping documents are provided with each order?

Accepted Answer

A typical documentary set includes the commercial invoice, packing list, bill of lading, certificate of origin, certificate of analysis and any inspection certificate (e.g. SGS). Additional documents such as SGS/CIQ or a certificate of insurance are provided when the contract or LC requires them.

Question 25

What are typical lead times for a bitumen order?

Accepted Answer

Lead time depends on grade, quantity, packaging and vessel availability. Once payment terms are in place, packed cargo is usually ready within a couple of weeks, with total transit time driven by the destination port. We confirm an indicative schedule on the quotation.

Question 26

Do you arrange insurance for shipments?

Accepted Answer

Under CIF terms we arrange marine cargo insurance covering the goods to the destination port. Under FOB or CFR terms insurance is the buyer’s responsibility, though we can facilitate a policy on request.

Question 27

What packaging options are available for bitumen?

Accepted Answer

We offer new steel drums (typically 150–220 kg), jumbo bags (FIBC/Cratered bags around 300 kg–1 MT), poly-bags, bitutainers and bulk vessel loading. The right option balances cost, handling at destination and the grade being shipped.

Question 28

What is a bitumen jumbo bag (FIBC)?

Accepted Answer

A bitumen jumbo bag, or FIBC (flexible intermediate bulk container), is a meltable or peelable bag holding roughly 300 kg to 1 tonne of bitumen. The bitumen is poured directly into a melter with the bag, reducing packaging waste compared with drums.

Question 29

How should bitumen drums be stored?

Accepted Answer

Store drums upright on a firm, dry surface, away from direct sunlight and ignition sources, and avoid stacking beyond the recommended height to prevent deformation. Keep the storage area ventilated and observe the product’s safe handling temperature.
