该方法包括通过计算从混合物样品中回收的氢氧化钙Ca（OH）2，定量测定热拌沥青（HMA）中石灰的百分比。通过在HMA中钻孔并收集钻孔粉尘获得样本。对样品进行酸过滤器煮沸和清洗，并使用原子吸收（AA）或离子交换色谱（IEC）进行分析。本标准以前被指定为临时标准TP 72。

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.
