本文件描述了用点火法测定沥青混合料样品粘合剂含量的试验方法。因此，它是用溶剂提取粘合剂的更传统方法的替代方法。该方法可用于评估混合料组成，因为剩余的骨料可用于确定骨料级配和密度，前提是骨料颗粒在达到的温度下不会过度分解。该结果可用于过程控制或混合物合规性检查。然而，在进行分析之前，需要对混合物进行校准，无论是对完整混合物还是对其每种组成材料进行校准，这使得该方法更容易用于经常使用的混合物，而不是用于来自不同骨料来源的各种不同混合物。该试验方法同样适用于含有未改性或改性粘合剂的混合物的分析，因为当使用混合物校准时，必须对每种被检查的混合物校准该方法。如有疑问/争议，以实验室制备的沥青混合料（见A.1和A.2）为基础确定校准值为参考方法。

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.
