Bitumen Standards and Grades
Explore global bitumen standards and grades, including ASTM, EN, SLS, AASHTO, CAP, and GOST specifications. Learn how international standards define bitumen properties and testing methods.
Understanding International Bitumen Grades
Bitumen Standards and Grades
Bitumen quality and performance are defined by international standards and grading systems. These standards ensure that the material used for road construction, waterproofing, and industrial applications meets specific physical, chemical, and performance requirements.
At Bernet Bitumen, we follow globally recognized specifications such as ASTM, EN, SLS, AASHTO, GOST, and CAP to guarantee consistent product quality and compliance with regional regulations.
Importance of Bitumen Standards
Bitumen standards establish the testing methods, classification, and performance benchmarks for each type of bitumen.
They help ensure:
- Consistent product quality worldwide
- Compatibility with regional climates and construction standards
- Safe transportation and use across international markets
Defining Quality Through Standards
Overview of Global Bitumen Standards
Below are the major standards used internationally, each with specific test codes and procedures that define penetration, softening point, viscosity, ductility, and other key bitumen properties.
Global Standards
Defines international harmonization of testing and performance methods across different regions.
SLS Bitumen Standards
Sri Lanka Standards (SLS) specify local climate-adjusted grades and methods.
EN Bitumen Standards
European Norm (EN) standards define product categories and test methods across the EU.
ASTM Bitumen Standards
ASTM defines key bitumen test methods used globally, including penetration, viscosity, and ductility.
CAP Standard Bitumen
China’s CAP standards regulate bitumen quality under national construction requirements.
AASHTO Bitumen Standards
AASHTO standard used widely in the USA for road construction & highway.
GOST 52056 Standards
Russian Federation standards defining testing methods for viscosity and performance grades.
Bitumen Grades and Classification
Different standards classify bitumen based on its penetration value, viscosity, and performance under temperature stress.
Common grades include:
- Penetration Grades (e.g., 40/50, 60/70, 80/100)
- Viscosity Grades (VG-10, VG-30, VG-40)
- Performance Grades (PG 58-22, PG 64-16)
These classifications help engineers and buyers select the right bitumen type for their projects based on climate and road design requirements.

Understanding the Table
This comparison shows how different organizations use similar scientific methods under various regional codes:
- ASTM, AASHTO, and EN standards are internationally harmonized, used by most laboratories worldwide.
- SLS adapts ASTM methods to tropical climates such as Sri Lanka.
- GOST emphasizes viscosity and low-temperature flexibility for colder regions.
- CAP (China) integrates GB/T and JTG codes for national road projects.
