4 cards from this section. Quick, good the night before a test.
What primary environmental factor contributes to thermal cracking?
Think about changes in hot and cold weather.
What happens to bitumen when it oxidizes?
Consider the role of oxygen.
What is the primary cause of thermal cracking in bituminous materials?
Think about the effect of seasons on material performance.
Cracking is less likely to occur in warm climates compared to cold ones. True or False?
Reflect on how temperature affects materials differently.
Design a laboratory test that could simulate the effects of thermal cracking on a bituminous sample over time. Outline the steps involved.
Consider how real-world conditions would simulate wear on a sample.
Given a case study in a tropical climate, assess how environmental factors differ from those in a cold climate regarding crack formation in pavements.
Think about how different climates expose materials to different stresses.
