Challenge Problems
Push your limits with challenges.
Question 1
Given a mix design where the maximum stability is 900 kg at 6% bitumen, bulk specific gravity is 2.30 at 6%, and air voids calculated at 2%, what would be the optimum bitumen content?
💡 Hint: Use the average formula for these three percentages.
Question 2
If a mix shows high stability but low flow, indicate two adjustments that could be made to improve the mix performance.
💡 Hint: Think about how preventing cracking can be achieved with flow adjustments.
