Question 1
What does G_t represent in Marshall Mix Design?
- A measure of air voids
- Theoretical specific gravity
- Bulk specific gravity
💡 Hint: It’s the gravity that relates to the mixture's theoretical density.
Question 2
True or False: G_m includes the air voids in the mixture.
- True
- False
💡 Hint: Think about how G_m differs from G_t.

Challenge Problems
Push your limits with challenges.
Question 1
Given the specific gravities 2.65 for coarse aggregate, 2.50 for fine aggregate, and 1.03 for bitumen; what would be the G_t for a mix with weights 900g, 1300g, 150g?
💡 Hint: Make sure to check your weights against specific gravities.
Question 2
In a mix with 30% air voids and the volume of bitumen calculated as 18%, what is the VMA?
💡 Hint: Just a simple addition to find total voids.
