What is AC-20 bitumen?
AC-20 bitumen is a medium-to-high viscosity grade in the asphalt cement classification, carrying a target viscosity of 2000 poises at 60°C. Well suited to moderate and hot climates, AC-20 bitumen offers strong heat stability and durability, making it a popular choice for busy highway construction projects.
Engineers specify AC-20 bitumen for roads carrying moderate-to-heavy traffic in regions with warm seasonal temperatures. Its firm consistency helps AC-20 bitumen resist rutting and deformation under sustained loads, ensuring stable, long-lasting pavement performance across highways, urban roads, and hot mix asphalt applications nationwide.
