Penetration Grade Bitumen is one of the most widely used categories of paving bitumen in road construction and asphalt production. This conventional classification system is based primarily on the penetration value of the binder under standardized laboratory conditions.
Penetration Grade Bitumen is available in different grades, with lower penetration values generally indicating harder binders and higher values indicating softer binders.
Sepidman Pars supplies a range of Penetration Grade Bitumen suitable for various road construction, asphalt production, and infrastructure applications.
Available Penetration Grades
40/50
60/70
85/100
100/120
Each grade offers different consistency and temperature characteristics. The appropriate grade should be selected according to climate, traffic loading, asphalt mixture design, construction requirements, and applicable standards.
Bitumen 60/70, for example, is a widely used paving grade in many road construction applications, while softer grades may be selected when greater flexibility is required under specific climatic conditions.
For project-specific requirements, technical data and test results should be reviewed before final material selection.
