3 cards from this section. Quick, good the night before a test.
What does the Beam Fatigue Test evaluate?
Think about what stresses pavements experience from vehicles.
What type of stress is measured in the Indirect Tensile Fatigue Test?
Recall how the loads are applied in this test.
What is the purpose of the Beam Fatigue Test?
Think about how pavements are loaded.
True or False: Fatigue testing can predict when pavement cracks will develop.
Consider the significance of the fatigue life curve.
Design a research proposal that outlines how you would study the effects of different aggregate types on the fatigue properties of asphalt mixes combining both Beam Fatigue Test and Indirect Tensile Test.
Think about how aggregate types could affect performance.
Analyze a fictional scenario where a city has experienced premature cracking in newly paved roads. Using knowledge about fatigue testing, explain how you would identify the cause and propose solutions.
Refer back to how the tests can inform design improvements.
