BS EN 12697-39:2020 pdf free.Bituminous mixtures – – Test methods Binder content by ignition.
BS EN 12697-39 1 Scope  This document describes a test method for the determination of the binder content of samples o 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 regulartly used mixtures rather than with an extensive range of different mixtures from diferent aggregate sources. The test method is equally suitable for the analysis of mixtures containing umdified or modified binders because the method has to be  llbrated for each mixture being checked when cllbration on mixtures is used. In case of doubt/dispute, the determination of the calibration  alue based on laboratory-prepared bituminous mixtures (see A.1 and A.2) is the reference method. 2 Normative references The fllowing documents are referred to in the text in such a way that some or all of their content constitutes requirements of this document For dated references, only the edition cited applies.
