26.3.2. Bulk specific gravity of mix G m

Try these first

1. 1.

   Define bulk specific gravity (G m).

   Hint

   Think about what specific gravity measures.

2. 2.

   If W m is 1500g and W w is 1400g, what is G m?

   Hint

   Use the G m formula.

3. 3.

   What is the formula for calculating bulk specific gravity?

   Hint

   Remember to account for the difference in weights.

4. 4.

   True or False: Bulk specific gravity increases as the volume of air voids decreases.

   Hint

   Consider how density is influenced by voids.

5. 5.

   Given a mix with W m = 2000g and W w = 1900g, calculate G m and discuss the implications if the calculated G m is significantly high.

   Hint

   Analyze the relationship between density and voids.

6. 6.

   Design a scenario with varying G m values (low, medium, high) and predict their impact on pavement life. Justify each case.

   Hint

   Use examples from real-world applications to illustrate your points.
