22.2.7. Freedom from deleterious particles

Try these first

1. 1.

   Define deleterious particles in the context of pavement construction.

   Hint

   Think about materials that could weaken the pavement.

2. 2.

   What types of materials should be avoided in aggregates?

   Hint

   Consider what could interfere with the bond between materials.

3. 3.

   What are deleterious particles?

   • Harmful materials in aggregates
   • Non-harmful materials
   • All aggregates

   Hint

   Think about what 'deleterious' means.

4. 4.

   True or False: All aggregates can be used regardless of their cleanliness.

   • True
   • False

   Hint

   Consider the importance of quality in materials.

5. 5.

   Suppose you are assessing the aggregates for a new pavement project and find a significant amount of clay and silt present. What implications might this have on your project's quality, and what recommendations would you give?

   Hint

   Consider the long-term consequences of using poor-quality materials.

6. 6.

   You have been tasked with developing specifications for a new aggregate supplier. What key characteristics regarding deleterious particles should you include, and why are they critical for pavement construction?

   Hint

   Reflect on what previous discussions have highlighted regarding imperfections in aggregates.
