3 cards from this section. Quick, good the night before a test.
What does the term 'air voids' refer to in asphalt mixtures?
Think about what happens to air when it's mixed with solid materials.
What is the ideal percentage of air voids in an asphalt mixture?
What range did we discuss in class?
What is the purpose of calculating air voids Vv in asphalt?
Think about how voids can influence material properties.
True or False: The ideal air voids percentage in an asphalt mixture is above 5%.
Recall the ideal range we discussed.
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.
Use the formula Vv = (Gt - Gm) / Gt × 100.
Design a quality analysis report that evaluates a mix for its air voids content and what it suggests about its longevity.
Initiate by determining the specific gravities and compute the air void percentage before drafting your report.
