Quality by ASTM
ASTM Bitumen Standards
Detailed guide to ASTM bitumen standards, including penetration, viscosity, and performance test methods used globally in bitumen evaluation.
American Specifications for Asphalt and Bitumen
American Society for Testing and Materials (ASTM) Bitumen Standards
ASTM (American Society for Testing and Materials) International defines the most widely recognized testing methods for bitumen, asphalt, and related materials.
These standards set benchmarks for consistency, safety, and performance.
Standard Codes for Bitumen Properties
Property | ASTM Code | Description |
Penetration | ASTM D5 | Measures consistency and grade classification |
Softening Point | ASTM D36 | Identifies temperature sensitivity |
Ductility | ASTM D113 | Determines elasticity and flexibility |
Viscosity | ASTM D2171 / D4402 | Evaluates flow resistance |
Flash Point | ASTM D92 | Measures ignition safety level |
Methods for Different Bitumen Types
- Paving Grade Bitumen: ASTM D946
- Cutback Bitumen: ASTM D2027
- Emulsion Bitumen: ASTM D244
- Modified Bitumen: ASTM D5892
Each method includes procedures for sample conditioning, testing, and result interpretation.
International Recognition
ASTM standards are accepted worldwide, forming the basis for AASHTO and ISO correlations.
Bernet Bitumen adheres strictly to these specifications for consistent quality across global shipments.
