2 cards from this section. Quick, good the night before a test.
Define bulk density.
Think about what mass means in relation to volume.
What do voids represent in aggregates?
Consider the structure of aggregates.
What does bulk density measure?
Think of what mass means in overall terms.
True or False: Voids in aggregates are beneficial for strength.
Think about how they impact material requirements.
You have two types of aggregates, A and B, with bulk densities of 1.5 g/cm³ and 2.2 g/cm³. If you need a total of 2000 kg for a construction project, how much volume will each aggregate take?
Always remember to convert kg to g for density unit consistency.
Discuss how high voids could affect total material requirements in a road mix design.
Consider both material costs and pavement longevity.
