This method covers the quantitative determination of the percentage of lime in hot mix asphalt (HMA) by calculation of the calcium hydroxide, Ca(OH)2, recovered from a sample of the mixture. A specimen is obtained through drilling into the HMA and collecting the drilling dust. The specimen is subjected to an acid filter boil and wash and is analyzed using either Atomic Absorption (AA) or Ion Exchange Chromatography (IEC).This standard was formerly designated as provisional standard TP 72.
