Penetration Grade Bitumen – EN Standards and Grades
Penetration grade bitumen is a cornerstone material in road construction, paving, and waterproofing projects, known for its exceptional durability and flexibility. Under the EN (European Norm) standard, bitumen is classified based on its penetration values to meet diverse climatic and structural needs. This page delves into EN-standard penetration grades such as 20/30, 30/45, 35/50, 40/60, 50/70, 70/100, 100/150, and 160/220.
What is Penetration Grade Bitumen?
Penetration grade bitumen is categorized based on its hardness or softness, determined by the penetration value (measured in tenths of a millimeter). This measurement is performed under specific conditions as per EN 1426 standards. EN-standard grades are engineered for diverse applications, offering unparalleled performance under various temperatures and loads.
Grades of Penetration Bitumen Under EN Standards
Below is a comprehensive overview of penetration-grade bitumen under EN standards:
| Grade | Penetration (mm) | Softening Point (°C) | Application |
|---|---|---|---|
| 20/30 | 20 to 30 | High | Heavy-duty roads in hot climates. |
| 30/45 | 30 to 45 | Medium | Industrial areas and high-load pavements. |
| 35/50 | 35 to 50 | Medium | High-traffic urban roads. |
| 40/60 | 40 to 60 | Moderate | General road construction. |
| 50/70 | 50 to 70 | Moderate | Highways and medium-traffic pavements. |
| 70/100 | 70 to 100 | Medium | Low-traffic pavements and maintenance. |
| 100/150 | 100 to 150 | Low | Flexible pavements in colder climates. |
| 160/220 | 160 to 220 | Very Low | Temporary and low-load roads. |
