bitumen supplier in china with chinese standard
China’s bitumen production and market insights
China’s demand for bitumen continues to grow rapidly as the country engages in large-scale infrastructure development. With an annual production capacity of 33 million tons, Chinese manufacturers play a significant role in both domestic and international markets. Additionally, China imports around 20 million tons of bitumen each year, sourced primarily from Korea and Thailand. Meanwhile, Basekim has been a reliable supplier to the Chinese market since 2006, consistently ensuring that all products meet Chinese standards and satisfy customer expectations.
Understanding Chinese bitumen standards
When it comes to ensuring product quality, bitumen in China follows strict and detailed standards. To explain further, the most notable difference between Chinese standards and ASTM lies in ductility requirements. For example, the Chinese standard mandates a ductility of 100 cm at 15°C, whereas ASTM specifies this at 25°C. Nevertheless, it is important to note that most other indexes remain identical, providing reliable performance across specifications.
Different grades of bitumen in China
bitumen supplier in china to accommodate a variety of applications, bitumen in China is classified into different grades based on penetration levels, ductility, and softening points. This classification allows users to select the ideal grade for specific projects and climatic conditions.
– Penetration levels:
For instance, No. 30 bitumen has a penetration range of 20–40, while No. 70 bitumen offers a range of 60–80.
– Ductility differences:
Moreover, No. 30 bitumen guarantees ductility ≥50, whereas No. 70 bitumen ensures ductility ≥100.
– Softening points:
In addition, No. 30 bitumen features a softening point of 55–72°C, while No. 70 bitumen provides a range of 44–54°C.
Additionally, comparing 70# and 90# grades reveals further differences in softening points, penetration, ductility, and viscosity. These variations make these grades suitable for a wide range of uses and environmental conditions.
Regional usage of bitumen grades in China
Given the country’s vast size and diverse geography, regional climates significantly influence bitumen grade preferences. For instance, No. 10 bitumen, bitumen supplier in china with a higher penetration, is softer and more appropriate for colder regions in the north. Conversely, No. 70 bitumen, being harder, performs better in the warmer southern areas.
Furthermore, within Shandong province, preferences for bitumen grades vary depending on the region. For example, northern and western parts of Shandong often use No. 90 or even No. 110 bitumen in colder areas. On the other hand, southern Shandong typically relies on No. 70 bitumen.
Moreover, regional supply and demand dynamics affect pricing. For example, in the north, where 70-grade bitumen sees less usage, surplus inventory often leads to lower prices. Similarly, in the south, where 90-grade bitumen is less common, it may be priced more competitively.
Specifications for petroleum asphalts in China
To ensure consistent performance and reliability, petroleum asphalts for road construction in China adhere to well-defined standards. For instance, some key standards include:
– GB/T 15171-2017, which specifies requirements for road and bridge asphalt.
– GB/T 4509-2010, which outlines softening point tests using the ring-and-ball method.
– GB/T 8161-2008, which describes the Fraass breaking point determination method.
– GB/T 4508-2010, which specifies the procedure for testing bitumen penetration.
Popular bitumen grades in China
70A bitumen (AH70):
This grade is highly suitable for heavy-traffic roads, offering a penetration range of 60–80 and a softening point of ≥46°C. Furthermore, its high dynamic viscosity and flash point ensure durability in demanding applications.
90A bitumen (AH90):
Offering a higher penetration range of 80–100 and a softening point of ≥45°C, this grade excels in flexibility and viscosity, making it a versatile choice for different environments.
SBS modified bitumen for enhanced performance
For projects that demand superior flexibility and durability, SBS-modified bitumen stands out as an excellent option. For example, it features enhanced penetration index, elastic recovery, and softening points, making it ideal for heavy-traffic roads and critical infrastructure.
