Challenge Problems
Push your limits with advanced challenges
Calculate the Gt, Gm, and Vv for a specimen with the following data: W1=500g, G1=2.5, W2=300g, G2=2.6, Wb=200g, Gb=1.0, with the specimen weight in air as 1500g and in water as 1200g.
💡 Hint: Verify the input values and calculations step by step.
Discuss how increasing the percent air voids (Vv) can affect the long-term performance of asphalt mixes.
💡 Hint: Think about what happens when there are too many air pockets in materials exposed to heavy loads.
