4 cards from this section. Quick, good the night before a test.
What is the minimum required Marshall stability value?
Refer to the specifications for asphalt mix design.
What is the typical percentage range for air voids in asphalt mixes?
Think about the optimal performance of pavements.
What is the primary parameter for determining optimum bitumen content?
Reflect on what the strength of materials relies upon.
True or False: The maximum flow value indicates favorable conditions in asphalt mixes.
Consider how flow correlates with stiffness in the mix.
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?
Use the average formula for these three percentages.
If a mix shows high stability but low flow, indicate two adjustments that could be made to improve the mix performance.
Think about how preventing cracking can be achieved with flow adjustments.
