Challenge Problems
Push your limits with challenges.
Question 1
Given a set of asphalt mixes, calculate the ideal volume of air voids needed for optimal performance in each and check if they meet the range standards.
💡 Hint: Use the formula Vv = (Gt - Gm) / Gt × 100.
Question 2
Design a quality analysis report that evaluates a mix for its air voids content and what it suggests about its longevity.
💡 Hint: Initiate by determining the specific gravities and compute the air void percentage before drafting your report.
