Bituminous mixtures - Test methods - Part 39: Binder content by ignition
Also Known As:
The DIN EN 12697-39 standard outlines a test method for determining the binder content of bituminous mixtures through ignition. This method offers an alternative to solvent extraction, which has been traditionally used for this purpose. By measuring the remaining aggregate after ignition, the method allows for the determination of aggregate gradation and density, and can be used for evaluating mixture composition.
The results obtained from this test method can be used for process control and to ensure compliance with mixture specifications. However, it is important to note that the method requires calibration of the mixture being tested, either as a whole or its individual components. This makes it more suitable for regularly used mixtures rather than a wide range of different mixtures with varied aggregate sources.
The test method described in this standard is applicable to both unmodified and modified binders. However, the calibration process must be carried out for each specific mixture, making it necessary to have detailed knowledge of the composition in order to accurately interpret the test results. In cases of doubt or disputes, the reference method for determining the calibration value is based on laboratory-prepared bituminous mixtures.
