3. If the grade of two bitumen samples are 30/40 and 80/100, then in which sample theductility value will be more. Why?

Answer»

The grade 80/100 means.. that bitumen will have a penetration between 8mm to 10 mm

and for 30/40...the penetration will be 3mm to 4 mm

so, 80/100 is more ductile due to higher penetration range.
