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 (Pba);
g. Find all the volumetric properties and mass quantities as indicated on the phase diagram and recalculate parts c, d, e, and f from this diagram.
