The AS/NZS 2891.9.1:2014 standard provides guidelines for determining the bulk density of compacted asphalt using a waxing procedure. The purpose of this standard is to ensure accurate and reliable measurements of the asphalt's density. It should be noted that the method described in this standard may not yield consistent results for relatively thin samples, such as those with a thickness less than 2.5 times the nominal size of the asphalt. This is because thinner samples are more prone to surface voids, which can affect the accuracy of the density measurements. This limitation is especially relevant for larger-sized mixes with larger surface voids, such as nominal size 14 mm asphalt or stone mastic asphalt.
