Bitumen 60/90 — A Wider-Tolerance Bridge Grade
Spanning 60/70 and 70/100 for more forgiving field performance.
Bitumen 60/90 bridges 60/70 and 70/100, giving buyers a grade with a wider penetration tolerance than either — useful where local aggregate or climate conditions produce variable field performance with a tightly-banded grade, and a slightly more forgiving specification window improves consistency in practice. It behaves close to 60/70 at the lower end of its range and close to 70/100 at the upper end, making it a practical compromise rather than a distinct performance category.
