An asphalt mixture has the following composition and properties: Bulk specific gravity = 2.31 Theoretical maximum specific gravity = 2.50 Coarse aggregate 65%, Bulk specific gravity = 2.72 Fine aggregate 30%, Bulk specific gravity = 2.66 Asphalt 5%, Specific gravity = 1.01 Calculate the following: a. Bulk specific gravity of aggregates (Gsb); b. Effective specific gravity of aggregates (Gse); c. %Air void content (%AV); d. Voids in Mineral Aggregate (VMA); e. Voids filled with asphalt (VFA); f. Percent asphalt absorption...

A compacted asphalt concrete specimen contains 4.8% asphalt binder by weight of total mix and aggregate blend with blended specific gravity of 2.689. The average bulk density of the compacted specimen is 2.414 g/cm3 . Ignoring absorption of aggregate particles, 1) compute the VTM, VMA, VFA, and D/B of the specimen. 2) Draw the phase diagram of this asphalt mixture. - Asphalt binder specific gravity, Gb: 1.03 - Passing #200 fine fillers (%): 4.7 %

Relate aggregates, concrete, asphalt, cement materials individually, and relate each material to the other materials. For example, how do they relate to a concrete or asphalt mixture? The goal is to demonstrate a thorough understanding of each material and their relationships to each other. Focus on a discussion and the significance of individual material groupings (aggregates, concrete (including Modulus Of Elasticity), asphalt, and cement), and explain in detail their importance to quality concrete and asphalt mixtures. Talk about “What, How,...
