Chinese Grade Bitumen AH 110

Chinese Grade Bitumen AH 110 offers a relatively soft paving-grade bitumen for road construction, asphalt production, maintenance work, and other infrastructure applications. Manufacturers produce this petroleum-based binder from carefully processed refinery residue and control its physical properties to meet the requirements of Chinese paving bitumen standards.

Road contractors choose AH 110 when they need a softer asphalt binder with suitable adhesion, flexibility, and workability. In addition, the grade can perform effectively in applications where pavement designers need greater flexibility at moderate or lower service temperatures.

Basekim supplies and exports Chinese Grade Bitumen AH 110 for international projects. The company can support bulk orders, suitable export packaging, documentation, and international shipment requirements.

What Makes Chinese Grade Bitumen AH 110 Different?

The AH classification identifies penetration-grade paving bitumen commonly associated with Chinese road construction specifications. The numerical designation generally reflects the penetration range and therefore helps buyers understand the relative hardness or softness of the binder.

Chinese Grade Bitumen AH 110 provides a softer consistency than lower-penetration grades such as AH 70. Consequently, it can offer improved flexibility where pavement conditions require a binder that can tolerate movement and temperature changes.

At the same time, engineers must consider climate, traffic volume, aggregate type, pavement design, and local specifications before selecting a final asphalt binder.

AH 110 can provide several important properties:

• Good adhesion to suitable mineral aggregates

• Flexible behavior under appropriate service conditions

• Reliable asphalt mixture workability

• Consistent binder distribution during mixing

• Suitable waterproofing characteristics

• Controlled penetration and softening behavior

• Good compatibility with common hot-mix asphalt systems

Therefore, contractors can use this grade in several pavement construction and maintenance processes.

Chinese Grade Bitumen AH 110 Specifications

Technical specifications play a major role in every bitumen purchase. Buyers usually evaluate penetration, softening point, ductility, flash point, solubility, and aging characteristics before approving a shipment.

The following table presents typical reference properties for AH 110. Actual values can vary according to the applicable Chinese standard, refinery source, contract requirements, and production batch. Therefore, buyers should always confirm the latest TDS and COA before placing an order.

Because standards and project specifications may differ, purchasing teams should request a Certificate of Analysis for the actual shipment rather than rely only on general reference values.

Penetration and Consistency

Penetration represents one of the most important indicators when evaluating paving bitumen. Laboratories measure how far a standardized needle penetrates the binder under controlled conditions.

A higher penetration value usually indicates a softer binder. Therefore, AH 110 normally offers greater softness than harder grades such as AH 50 or AH 70.

This property influences asphalt flexibility, mixing performance, temperature sensitivity, and pavement behavior. However, engineers should never select bitumen according to penetration alone. They should also evaluate softening point, ductility, aging resistance, climate conditions, and traffic loading.

Softening Point and Temperature Performance

The softening point indicates the temperature at which the material reaches a specified level of softness under laboratory conditions.

Since Chinese Grade Bitumen AH 110 belongs to the softer side of paving-grade binders, its thermal behavior differs from that of harder penetration grades. As a result, road designers should match the binder with the expected pavement temperature range.

For example, extremely hot climates and very heavy traffic may require a harder binder or a modified asphalt solution. Conversely, a softer binder can provide useful flexibility where cold-temperature cracking creates a greater concern.

Therefore, proper binder selection can significantly affect pavement durability.

Ductility and Flexibility

Ductility shows how far bitumen can stretch before breaking under controlled test conditions. This characteristic helps engineers evaluate the binder’s ability to accommodate deformation.

Good ductility supports pavement flexibility. Moreover, it can help asphalt mixtures resist certain forms of cracking when engineers design the entire mixture correctly.

However, aggregate properties, asphalt content, air voids, pavement thickness, compaction, and construction quality also influence final road performance. For this reason, contractors should view the binder as one part of the complete pavement system.

Main Applications of AH 110 Bitumen

Contractors mainly use AH 110 as an asphalt binder for road and infrastructure applications. Its relatively soft consistency can support projects that require greater flexibility and suitable workability.

Common applications include:

Hot Mix Asphalt Production

Asphalt plants combine heated aggregates with controlled quantities of bituminous binder. AH 110 can coat properly prepared aggregates and create a cohesive asphalt mixture.

The plant must control temperature carefully because excessive heat can accelerate binder aging.

Road Construction

Contractors can use AH 110 in selected pavement layers when the project specification allows this grade. Engineers should evaluate local weather, axle loads, road classification, and mixture design before final approval.

Road Maintenance

Some maintenance mixtures may use softer paving binders because they need good workability and adhesion. Nevertheless, the exact formulation depends on the maintenance method and engineering requirements.

Flexible Pavement Systems

Flexible pavement relies on bituminous materials to bind aggregates while allowing controlled movement under traffic and environmental changes.

Because AH 110 offers relatively soft characteristics, it may fit specific flexible pavement designs where engineers prioritize binder flexibility.

AH 110 vs AH 70

Buyers often compare AH 110 with Bitumen AH 70 because both grades can serve paving applications.

The most important difference involves consistency. AH 110 generally provides a softer binder, while AH 70 offers greater hardness and usually better resistance to deformation under hotter or heavier-service conditions.

However, contractors should follow project specifications rather than select a grade only from a general comparison.

AH 110 vs AH 90

AH 90 generally sits between AH 70 and AH 110 in terms of relative softness.

Therefore, engineers may consider AH 90 when they need a balance between the harder characteristics of AH 70 and the softer behavior of AH 110. Still, final selection depends on laboratory testing, pavement design, climate, and applicable construction standards.

Production of Chinese Grade Bitumen AH 110

Refineries produce paving bitumen from heavy petroleum fractions that remain after crude oil distillation.

First, the refinery separates lighter petroleum fractions. Next, it processes the remaining heavy residue until the material reaches the required binder characteristics. Producers then control important parameters such as penetration, viscosity, softening point, ductility, and purity.

After production, laboratories test representative samples. Quality-control teams compare the results with the requested specifications. Finally, the supplier prepares the approved material for storage, packing, and shipment.

Consistent production and quality control remain especially important for large road construction projects because variations in binder properties can affect asphalt mixture behavior.

Storage and Handling

Companies should store AH 110 in suitable bitumen tanks, drums, or approved industrial containers.

Operators should prevent contamination from water, fuel, dust, chemicals, and incompatible materials. In addition, they should control heating carefully during storage and processing.

Excessive heating can damage bitumen and accelerate oxidation. Therefore, operators should heat only to the temperature necessary for pumping, mixing, or application.

Workers should also use proper protective equipment when handling hot material because heated bitumen can cause severe thermal burns.

Packaging Options for Export

International buyers often select packaging according to destination, unloading equipment, project consumption, and transportation cost.

Common export solutions can include:

New steel drums: Steel drums simplify handling and support conventional containerized shipments.

Jumbo bags: Suitable bitumen bag systems can reduce steel packaging requirements for certain destinations and operating conditions.

Bulk transportation: Large-volume projects may receive bitumen through bulk tankers, vessels, or specialized transport systems where infrastructure allows.

Before shipment, buyers should confirm packaging dimensions, net weight, container loading capacity, and destination-country requirements.

In addition, Incoterms can significantly affect the final quotation. An EXW, FOB, CFR, or CIF offer may show a different total cost structure.

Consequently, buyers should provide the required quantity, destination port, packaging, and required specification when requesting a commercial quotation.

Quality Control and Export Documents

Professional buyers usually require technical and commercial documentation before accepting an international shipment.

Depending on the contract, documents may include:

• Technical Data Sheet
