As part of mix design, a laboratory-compacted cylindrical asphalt specimen is weighed for determination of bulk-specific gravity. The following numbers are obtained:Dry mass in air = 1264.7 gramsMass when submerged in water = 723.9 gMass of saturated surface dry (SSD) = 1271.9 ga. What is the bulk-specific gravity of the compacted specimen (Gmb)?b. If the maximum theoretical specific gravity of the specimen (Gmm) is 2.531, what would be the air void content of the specimen in percent?

Question
As part of mix design, a laboratory-compacted cylindrical asphalt specimen is weighed for determination of bulk-specific gravity. The following numbers are obtained:
Dry mass in air = 1264.7 grams
Mass when submerged in water = 723.9 g
Mass of saturated surface dry (SSD) = 1271.9 g
a. What is the bulk-specific gravity of the compacted specimen (Gmb)?
b. If the maximum theoretical specific gravity of the specimen (Gmm) is 2.531, what would be the air void content of the specimen in percent?
