About us
At SRNT (Silk Road Nexus Traders), we help international buyers source the bitumen they need. As a trading company, we begin by understanding your requirements—from product type and grade to technical specifications, quantity, packaging and destination.
We review supply options and compare proposed terms to help you choose a product and price suited to your specifications and order requirements. Our aim is to bring together the quality you need, competitive pricing and clear commercial terms.
We offer bitumen of Iranian and Iraqi origin. Product grade, origin, technical documentation and delivery terms are confirmed for each enquiry.
About usOUR PRODUCTS
A paving binder classified by needle penetration at 25°C. Lower values indicate a harder binder and higher values a softer one; selection also depends on the specification, climate, traffic and mix design. For an enquiry, share the required penetration range, applicable standard and intended asphalt layer. Review the full test profile rather than choosing on the grade name or price alone.

A paving binder classified by resistance to flow, primarily at 60°C, with additional testing at 135°C. The VG designation is not interchangeable with a penetration grade without checking the complete specification. Share the specified VG grade and the mixing and laying requirements in your project documents. Compare the complete test limits, packaging and delivery conditions when reviewing an offer.

A binder selected for defined pavement design temperatures. Its laboratory profile considers the original binder and simulated ageing; climate, traffic, reliability and the project standard guide selection. The two temperature values identify the specified high- and low-temperature grade, not the air temperature on the delivery day. Send the required PG designation and project test requirements so the proposed binder can be reviewed against the same specification.

Controlled air blowing generally raises the softening point and lowers penetration. This harder industrial binder is selected around service temperature, substrate and the finished-product specification. Check both softening point and penetration when comparing grades, alongside the intended manufacturing or installation process. For an enquiry, describe the finished application and any required handling or packaging conditions.

Bitumen blended with petroleum solvent to reduce viscosity. RC, MC and SC identify rapid, medium and slow curing; the remaining binder develops as solvent evaporates. Confirm the grade, application and local handling requirements. Selection also depends on the approved work method and the conditions for curing at the job site. Include the specified curing family, viscosity grade and intended treatment in your enquiry; substitution with an emulsion requires a separate review.

Fine bitumen droplets dispersed in water with an emulsifier. Charge, setting behaviour and aggregate compatibility determine the right product. Emulsion and recovered-binder tests must be considered separately. Tack coats, surface treatments and cold mixes can call for different emulsion grades even on the same project. Share the intended treatment, aggregate information and specified setting class, together with the required tests and storage arrangements.

Modifiers adjust selected binder properties. The catalogue profiles cover polymer-modified paving binders described by PG grades. A PG designation alone does not prove modification; specify the polymer system and required tests. Rubber-modified and other systems can be reviewed separately. Review the requested performance profile together with evidence of the specified modification and compatibility with the mix design. Include the application, required grade and any ageing or deformation tests in the enquiry; a similar grade name is not enough to establish equivalence.

TAILORED SOLUTIONS
Start with your application. Refine against your specification.
PACKAGING SOLUTIONS
Steel drums are individual metal containers used to package selected bitumen grades for handling, storage and shipment. Drum specification, net weight, palletising and loading requirements are agreed for the selected product.
Request a Quote
Jumbo bags are large flexible containers for compatible bitumen grades. The bag construction, inner liner, support, net weight and unloading method are selected around the product and your receiving facilities.
Request a Quote
Bulk supply means delivery without individual drums or bags, using suitable tankers or other agreed bulk transport equipment. It requires compatible product handling, receiving facilities and loading and discharge arrangements for the route.

We review your product specifications, quantity, packaging and purchase terms with you.
We compare pricing, technical specifications and supply terms to support a more informed choice.
Agree the delivery point, responsibilities, documents and timing. We coordinate your order and shipment arrangements, keeping you informed with progress and delivery updates.
DOCUMENTS & QUALITY
Request documents that match your grade and shipment: TDS describes the product's technical profile, SDS explains safe handling, and COA records measured results for the identified batch.
A grade-specific technical reference covering product properties, specification limits and test methods. Review it against your project's requirements.
Guidance on hazards, safe handling, storage and emergency response. Request the current document applicable to your product.
Actual test results for a specific production batch. Match the batch number, test date and reported values to the agreed specification and shipment.

Applications
Both can make a binder easier to apply, but they are not interchangeable. Compare the carrier, curing behaviour, application requirements and buying questions.

Buying guide
Understand viscosity grading, avoid assuming VG30 and 60/70 are identical, and turn a grade request into a clear technical specification.

Technical guide
Read a performance-grade designation correctly and identify the project information needed before a binder is selected or a quotation is accepted.
LET’S MOVE FORWARD
Include the grade, tonnes, destination and preferred packaging. You can also attach a project specification for review.
