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 outlines a test method for determining the bulk density of bituminous specimens using gamma rays. This method involves using a transmission-type gamma radiation test bench to measure the density of cylindrical specimens or blocks, which can be prepared in the laboratory or cut from existing pavement. The thickness of the specimen body should ideally be between 30 mm and 300 mm.
It is important to note that this method is not suitable for materials containing slags or those with variable metal content or chemical composition. This is because such materials can affect the absorption of gamma rays. Therefore, the method is best used for homogeneous bituminous mixtures with known characteristics.
The document also emphasizes the need to adhere to safety regulations when working with gamma rays. As gamma radiation can be hazardous, proper safety precautions should be followed to protect personnel and ensure compliance with safety standards.
