WHAT IS CHINESE STANDERD BITUMEN ?
Chinese grade bitumen refers to bitumen produced for China. China is a significant producer and consumer of bitumen, and its bitumen industry has its own grading system based on the properties and specifications of the bitumen. The grades may vary depending on factors such as viscosity, penetration, softening point, and application. Chinese grade bitumen is used in various construction projects, including road paving, waterproofing, and roofing. Chinese standards for bitumen, also known as asphalt, are set by various regulatory bodies and organizations in China to ensure quality, consistency, and safety in its production and use. These standards cover various aspects of bitumen including its properties, classification, testing methods, and application requirements.
SOME KEY FOR CHINESE STANDARS FOR BITUMEN INCLUDE:
- GB/T 11145: Bitumen for road construction – Specification: This standard specifies the requirements for various grades of bitumen used in road construction, including penetration grade bitumen, viscosity grade bitumen, and performance grade bitumen.
- GB/T 16826: Determination of Penetration of Bitumen: This standard specifies a method for determining the penetration value of bitumen using a penetrometer, which measures the depth to which a standard needle penetrates the bitumen sample under specified conditions.
- GB/T 4509: Determination of Softening Point of Bitumen: This standard specifies a method for determining the softening point of bitumen using a ring-and-ball apparatus, which measures the temperature at which the bitumen softens and the two surfaces of the bitumen sample meet under specified conditions.
- GB/T 5079: Determination of Flash Point and Fire Point of Bitumen: This standard specifies a method for determining the flash point and fire point of bitumen using a Pensky-Martens closed-cup apparatus, which measures the temperature at which bitumen gives off vapors that can be ignited under specified conditions.
- GB/T 8150: Determination of Ductility of Bitumen: This standard specifies a method for determining the ductility of bitumen using a ductility meter, which measures the distance to which a standard briquette of bitumen can be stretched before breaking under specified conditions.
These standards are regularly updated and revised by relevant authorities in China to reflect advancements in technology, industry best practices, and changing requirements. Compliance with these standards is essential for manufacturers, suppliers, and users of bitumen to ensure product quality and performance.
WHAT IS BITUMEN 70 CHINESE GRADE?
In China, “Bitumen 70” likely refers to a specific grade of bitumen based on its penetration value. Bitumen grades are often classified based on their penetration value, which indicates the depth in tenths of a millimeter to which a standard needle penetrates the bitumen sample under specified conditions.
Therefore, “Bitumen 70” could refer to a penetration grade bitumen with a penetration value falling within the range of 60 to 70 tenths of a millimeter. This classification is commonly denoted as “Penetration Grade 60/70” in international standards.
It’s essential to consult the relevant Chinese standards or specifications to confirm the exact properties and applications of Bitumen 70 within the Chinese market. Additionally, the specific requirements and grading systems may vary depending on the standard or specification used by different manufacturers or regulatory authorities in China.
WHAT IS BITUMEN 90 CHINESE GRADE?
In the context of Chinese bitumen standards, “Bitumen 90” likely refers to a specific grade of bitumen based on its penetration value. Bitumen grades in China are often classified according to their penetration values, which indicate the depth in tenths of a millimeter to which a standard needle penetrates the bitumen sample under specific conditions.
Therefore, “Bitumen 90” could denote a penetration grade bitumen with a penetration value falling within the range of 80 to 100 tenths of a millimeter. This classification is commonly denoted as “Penetration Grade 80/100” in international standards.
To accurately understand the properties and applications of Bitumen 90 within the Chinese market, it’s important to refer to the relevant Chinese standards or specifications. These standards will provide detailed information on the specific requirements and grading systems used for bitumen in China.
WHAT IS BITUMEN A70 CHINESE GRADE?
Bitumen A70, in the context of Chinese grades, refers to a specific type of bitumen with certain properties and characteristics. However, without detailed information about the specific standards and specifications set by Chinese authorities or organizations, it’s challenging to provide an exact definition or description of Bitumen A70.
In China, bitumen grades are often classified based on parameters such as penetration, softening point, and viscosity. The designation “A70” likely indicates a specific grade of bitumen with characteristics tailored for certain applications or performance requirements. It’s possible that “A70” corresponds to a penetration-graded bitumen with specific penetration and softening point values.

WHAT ARE THE DIFFERENCES OF ASTM AND CHINESE GRADE
The American Society for Testing and Materials (ASTM) and Chinese standards often have differences in their specifications and testing methods for bitumen.
Some key differences between ASTM standards and Chinese standards for bitumen may include:
- Composition and Performance Requirements: ASTM standards typically outline specific requirements for the physical properties, chemical composition, and performance characteristics of bitumen. Chinese standards may have similar requirements but may also incorporate additional specifications tailored to local climate conditions and construction practices.
- Testing Methods: ASTM standards provide detailed procedures for testing various properties of bitumen, such as viscosity, penetration, softening point, and ductility. These testing methods are designed to ensure consistency and reliability in assessing bitumen quality. Chinese standards may utilize similar testing methods but may have variations or modifications to suit local testing facilities and equipment.
- Grading Systems: ASTM uses a grading system to classify bitumen based on penetration or viscosity ranges, such as ASTM D946 for penetration-graded bitumen and ASTM D3381 for viscosity-graded bitumen. Chinese standards may have their own grading systems based on different criteria, which may include penetration, softening point, or other parameters.
- Specifications for Asphalt Mixtures: ASTM standards provide guidelines for the use of bitumen in asphalt mixtures, including specifications for asphalt binder content, aggregate gradation, and performance grading. Chinese standards may have similar requirements but may also include additional specifications or performance tests tailored to local pavement design and construction practices.
- Regulatory Compliance: In some cases, bitumen products intended for use in specific countries or regions may need to comply with local regulatory requirements and standards, which may include ASTM standards, Chinese standards, or other international standards recognized by local authorities.
Overall, while ASTM and Chinese standards may share similarities in their approach to specifying bitumen properties and performance, differences in testing methods, grading systems, and regional considerations may exist. It’s essential for stakeholders in the bitumen industry to be aware of these differences and ensure compliance with relevant standards and specifications for specific projects or applications.
