15.3.2. Binder Testing and Equipment

Try these first

1. 1.

   What does DSR stand for?

   Hint

   It starts with 'D' and is used to measure rutting.

2. 2.

   Which test assesses low-temperature cracking?

   Hint

   It begins with a 'B' and involves bending.

3. 3.

   What does DSR measure in asphalt binders?

   • Low-temperature cracking
   • Rutting and fatigue performance
   • Long-term aging

   Hint

   Think about what stress testing relates to.

4. 4.

   True or False: The Rolling Thin Film Oven Test simulates long-term aging.

   • True
   • False

   Hint

   Remember the name specifies 'short-term'.

5. 5.

   You are tasked with selecting an asphalt binder for a highway in a region with extreme temperature fluctuations. Discuss how each test (DSR, BBR, RTFO, PAV) would influence your decision.

   Hint

   Consider the specific temperature extremes and their potential impacts.

6. 6.

   Create a testing protocol for a new binder to ensure its reliability. Include which tests to use and justify your choices based on expected performance needs.

   Hint

   Focus on the performance challenges this binder might face.
