Try these first

1. 1.

   What are nano-additives?

   Hint

   Think about their size and scale.

2. 2.

   Give an example of a bio-binder.

   Hint

   Consider renewable sources.

3. 3.

   What is the primary benefit of using nano-additives in bituminous materials?

   • Increased Cost
   • Improved Aging Resistance
   • Decreased Strength

   • True
   • False

   Hint

   Consider the nature of bio-binders.

5. 5.

   Design an experiment to test the effectiveness of a new bio-binder compared to standard bitumen at varying temperatures.

   Hint

   Consider control variables and necessary equipment for measuring performance.

6. 6.

   Propose a strategy to integrate nano-additives into an existing pavement technology while addressing potential challenges.

   Hint

   Think about stakeholder engagement and resource allocation.
