Gmb: bulk specific gravity of compacted mixture; Ndes: the number of gyrations specified to reach the target density of the mix and it is based on the estimated field density in the middle of its service life; Nmax: the number of gyrations based on an estimate of the final density expected in the field at the end of its service life after years of further densification by traffic; Nini: The number of gyrations used as a measure of mixture compactability during construction; Pbe: effective asphalt content, percent by the total mass of mixture; Gmm: maximum specific gravity of paving mixture (no air voids); Pb: asphalt content, percent by the total mass of mixture; Pba: absorbed asphalt, percent by mass of aggregate; TSR: tensile strength ratio; Ign. Furn. Calib.: ignition furnace calibration.
