3. 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 grams • Mass of Saturated Surface Dry (SSD) = 1271.9 grams %3D a.What is the bulk specific gravity of the compacted specimen (Gmb)? b.lf the maximum theoretical specific gravity of the specimen (Gmm) is 2.531, what would be the air void content of the specimen in percent? c. If the bulk specific gravity of aggregates is 2.675 and asphalt content is 5.5%, what is the voids in mineral aggregate and voids filled with asphalt in percent? Ignore absorption.
