2 cards from this section. Quick, good the night before a test.
Define temperature susceptibility in the context of bitumen.
Think about how temperature affects materials.
What is the softening point test used for?
Recall the tests we discussed in class.
What does temperature susceptibility measure in bitumen?
Think about what happens when it gets hot or cold.
True or False: Higher temperature susceptibility leads to better pavement performance.
Reflect on the stability of materials.
A city in a tropical climate experiences high temperatures during summer. Discuss the ideal properties of bitumen that should be used for road construction in this location and why.
Think about materials used in extreme climates.
Suppose a softening point test on a specific bitumen grade resulted in a temperature of 60°C. What implications does this have for using this bitumen in a northern climate with freezing winters?
What happens to materials in very cold versus very hot conditions?
