Try these first

1. 1.

   What are anti-stripping agents used for?

   Hint

   Consider the effects of moisture on pavement.

2. 2.

   Name one benefit of using polymer modified bitumen.

   Hint

   Link it to pavement performance under stress.

3. 3.

   What is the primary purpose of anti-stripping agents?

   • Improve flexibility
   • Enhance adhesion
   • Reduce cost

   Hint

   Think about moisture effects on pavement stability.

4. 4.

   True or False: Polymer Modified Bitumen enhances the oxidation resistance of bitumen.

   • True
   • False

   Hint

   Link it to the conditions that deteriorate bitumen.

5. 5.

   Evaluate how the different properties of anti-stripping agents used influence the long-term durability of pavement materials under heavy rainfall.

   Hint

   Consider case studies where specific agents have reduced maintenance costs.

6. 6.

   Analyze the impact of using CRMB in an area with high temperature variations and heavy traffic on the road's performance over time.

   Hint

   Reflect on performance metrics from areas that have implemented CRMB.
