38、s 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 o
39、f 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 or its component materials before an analysis can be carried out makes this method easier to use wi
40、th 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 whe
41、n 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. 2 Normative references The following referenced documents are indispensable for the application of this

47、 value is a specific, material-dependent value that normally is due to a loss of mass during the ignition from constituents in the mixture other than the binder. The principle of the binder content by ignition is based upon a pre-determination of the corrections for the constituents used in the mixt
48、ure, primarily the aggregate. NOTE 2 Mineral aggregate will show varying loss of mass during the test depending on their origin (petrographic composition). Examples of components that give rise to high corrections are limestone, hydrated lime and cellulose fibres. NOTE 3 Methods for determining the calibration values are given in Annex A (normative). 3.4 target temperature temperature to which the furnace would raise the sample in the test without the rise in temperature due to the exothermic reaction of burning the binder NOTE The target temperature (usually 540 C) is determined during
