2 cards from this section. Quick, good the night before a test.
What is ductility?
Think about how materials behave under tension.
What is the minimum ductility value specified by standards for bitumen?
Recall the thresholds set by the Bureau of Indian Standards.
What does the ductility test measure in bitumen?
Think about what this property signifies in terms of materials in construction.
True or False: A higher ductility value means a higher risk of cracking.
Consider what ductility means for stress and flexibility.
A sample of bitumen shows a ductility value of 65 cm. Discuss how this value might impact its performance in a hot climate.
Consider the meaning of ductility and environmental factors.
How could you experimentally determine the optimum temperature for pouring bitumen to achieve a higher ductility value?
Think of designing experiments and controlling variables to acquire accurate results.
