Bituminous mixtures - Test methods - Part 7: Determination of the bulk density of bituminous specimens by gamma rays
Also Known As:
The DIN EN 12697-7 standard provides a test method for determining the bulk density of bituminous specimens using gamma rays. The method involves using a transmission-type gamma radiation test bench to measure the bulk density of cylindrical specimens or blocks. These specimens can either be prepared in a laboratory or cut from an existing pavement. The thickness of the specimen body that is traversed by the radiation must be between 30 mm and 300 mm.
It's important to note that this method cannot be used for materials containing slags with variable metal content or chemical composition. This is because the presence of metal or certain chemical compositions may affect the absorption of gamma rays. The standard emphasizes the need to comply with safety regulations regarding the use of gamma rays.
