Show hintHide hint
Think about how easy the liquid flows.
Question 2.
What happens if the bitumen is too viscous during mixing?
Show hintHide hint
Consider the blending process.
3Question 3.
What role does viscosity play in bituminous materials?
- A) Determines the color of bitumen
- B) Influences the performance and stability of the mix
- C) Affects the cost of materials
Show hintHide hint
Think about mixing processes.
4Question 4.
True or False: High viscosity bitumen is preferable in warm climates.
- True
- False
Show hintHide hint
Consider how heat affects fluids.
Question 5.
A newly paved roadway in a hot climate starts developing ruts shortly after completion. Analyze the probable causes based on viscosity and temperature susceptibility.
Show hintHide hint
Consider how temperature affects material properties.
Question 6.
During a construction project, poor adhesion is observed, leading to stripping of the bitumen from aggregate. Propose methods to test and improve adhesion.
Show hintHide hint
Think about all factors affecting adhesion between materials.
