6.5.6. Water Absorption & Specific Gravity

Try these first

1. 1.

   What does water absorption in aggregates refer to?

   Hint

   Think about how aggregate interacts with water.

2. 2.

   What is the maximum allowable water absorption percentage for road aggregates?

   Hint

   Recall the acceptable limits discussed.

3. 3.

   What is the maximum percentage of water absorption allowed for road aggregates?

   • 1%
   • 2%
   • 3%

   Hint

   Recall the standards for aggregates.

4. 4.

   True or False: Specific gravity of aggregates typically falls below 2.5.

   • True
   • False

   Hint

   Consider the standard range.

5. 5.

   A construction project requires aggregates with low water absorption, but the available aggregates have an absorption rate of 3%. How would you address this issue during the mix design?

   Hint

   Think about blending different types of aggregates.

6. 6.

   Analyze how aggregates with a specific gravity of 2.7 would perform in a humid environment compared to those with a specific gravity of 3.0.

   Hint

   Consider density and its impact on performance.
