AR Grade Bitumen: What It Is & Where It’s Used | Industrial Applications
What are Uses of AR grade bitumen? AR Grade Bitumen, or Aged Residue Bitumen, is a performance-based asphalt binder that is graded according to its viscosity at a specified temperature. Unlike penetration-grade bitumen, which is tested at 25°C, AR grade bitumen is evaluated under conditions that simulate pavement aging — providing a more accurate prediction of long-term performance in hot climates and high-traffic areas. In this article, we will explain…
