109 TS-2d R 35-7 AASHTO where: Gmb = bulk specific gravity of the extruded specimen; Gmm = theoretical maximum specific gravity of the mixture; Ps = percent of aggregate in the mix; and Gsb = bulk specific gravity of the combined aggregate. Note 12 -- Although the initial trial binder content was estimated for a design air void content of 4.0 percent, the actual air void content of the compacted specimen is unlikely to be exactly 4.0 percent.
