12.3.3. Rutting Resistance Testing

Try these first

1. 1.

   What is the primary purpose of rutting resistance testing?

   Hint

   Think about what happens to roads under traffic.

2. 2.

   Name one test used for rutting resistance testing.

   Hint

   Recall the names of the tests we discussed.

3. 3.

   What is the main focus of rutting resistance testing?

   • Durability of mix
   • Resistance to permanent deformation
   • Temperature susceptibility

   Hint

   Think about what rutting actually is.

4. 4.

   The Wheel Tracking Test simulates which condition?

   • True
   • False

   Hint

   Remember how we discussed the tests' relationship to real-world conditions.

5. 5.

   Given data from a Wheel Tracking Test shows significant rutting well above acceptable limits, suggest potential modifications to improve the mix's performance.

   Hint

   Think about how mix composition affects performance.

6. 6.

   In a pavement design project, laboratory test results show low resistance to rutting in the proposed bituminous mix. Discuss possible reasons and potential solutions.

   Hint

   Focus on the properties of materials and their effects on performance.
