AS/NZS 2891.9.3:2014 standard outlines a procedure for measuring the bulk density of compacted asphalt specimens. The method is specifically suitable for use with open-graded mix or dense-graded mix that has surface voids larger than 3 mm in diameter. It should be noted that determining the density of relatively thin samples, where the asphalt thickness is less than 2.5 times the asphalt nominal size, may lead to more variable or less reliable results due to the small size and the increased influence of surface voids. This holds true, particularly for larger-sized mixes with large surface voids, such as nominal size 14 mm asphalt or greater, as well as stone mastic asphalt.
