本文件描述了一种测定混凝土样品中粘合剂含量的试验方法 通过点火的沥青混合物。因此，它是一种替代更传统的方法 使用溶剂提取粘合剂。该方法可用于混合物成分的评价 由于剩余骨料可用于确定骨料级配和密度， 前提是在达到的温度下，骨料颗粒不会发生过度分解。 结果可用于过程控制或混合物合规性检查。然而，需要 用于校准整个混合物或其每种成分材料上的混合物 另外，在进行分析之前，这种方法更容易与经常使用的方法一起使用 混合料，而不是来自不同骨料来源的大量不同混合料。 本试验方法同样适用于含有未改性或改性混合物的分析 粘合剂，因为在校准时，必须针对每种被检查的混合物校准该方法 使用混合物。如有疑问/争议，应根据 实验室制备的沥青混合料（见A.1和A.2）是参考方法。交叉引用:EN 12697-28EN 12697-1EN 12597EN 12697-14EN 12697-27EN 12697-2EN 1097-6ISO 5725（所有部分）。购买本文件时可获得的所有现行修改件均包含在购买本文件中。

This document describes a test method for the determination of the binder content of samples of bituminous mixtures by ignition. As such, it is an alternative to the more traditional method of extracting the binder using solvents. The method can be used for evaluation of mixture composition because the remaining aggregate can be used for determining aggregate gradation and density, provided excessive breakdown of the aggregate particles does not occur at the temperature reached. The results can be used for process control or checks on the compliance of mixtures. However, the need for calibration of a mixture, either on the complete mixture or on each of its component materials separately, before an analysis can be carried out makes this method easier to use with regularly used mixtures rather than with an extensive range of different mixtures from different aggregate sources. The test method is equally suitable for the analysis of mixtures containing unmodified or modified binders because the method has to be calibrated for each mixture being checked when calibration on mixtures is used. In case of doubt/dispute, the determination of the calibration value based on laboratory-prepared bituminous mixtures (see A.1 and A.2) is the reference method.Cross References:EN 12697-28EN 12697-1EN 12597EN 12697-14EN 12697-27EN 12697-2EN 1097-6ISO 5725 (all parts)All current amendments available at time of purchase are included with the purchase of this document.
