scope:

This Standard sets out the method for determining the bulk density by measurement of compacted asphalt specimens. The method is particularly appropriate for use with opengraded mix or dense-graded mix with surface voids larger than 3 mm diameter.

NOTE: Determining the density of relatively thin samples (e.g. where the asphalt thickness is less than 2.5 times the asphalt nominal size) may result in more variable or unreliable results due to the small size and the increased influence of surface voids. In particular, this is applicable to larger sized mixes with large surface voids such as nominal size 14 mm asphalt or greater and or stone mastic asphalt.
