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. |
