American Standard (AC Grades)
Viscosity-grade bitumen, specifically classified under the American Standard, is a premium choice for diverse road construction and industrial applications. This page offers a comprehensive guide to the AC-grade viscosity bitumen, including grades such as AC 2.5, AC 5, AC 10, AC 20, AC 30, and AC 40. We also explore its packing methods, quality standards, applications, and provide an option to request a custom quote for your specific project needs.
American Standard viscosity grades are defined based on their flow properties, measured in centipoise (cP) or stokes. The AC grades, ranging from AC 2.5 to AC 40, cater to different climatic conditions and project requirements. Each grade is tailored for specific applications, ensuring optimal performance, longevity, and resistance to wear and tear.
Grades of Viscosity Bitumen (American Standard)
| Grade | Absolute Viscosity @ 60°C (Poise) | Kinematic Viscosity @ 135°C (cSt) | Applications |
|---|---|---|---|
| AC 2.5 | 250 | 80+ | Cold climates, light traffic roads. |
| AC 5 | 500 | 120+ | Moderate climates, secondary roads. |
| AC 10 | 1000 | 160+ | Highways, urban roads. |
| AC 20 | 2000 | 240+ | Heavy-duty highways and industrial areas. |
| AC 30 | 3000 | 320+ | High-load pavements in hot climates. |
| AC 40 | 4000 | 400+ | Extreme climates and industrial pavements. |
Applications of AC Viscosity-Grade Bitumen
- AC 10 and AC 20 grades are widely used for highways and urban streets.
- AC 2.5 and AC 5 grades are suitable for regions with colder temperatures.
