Bituminous mixtures - Test methods for hot mix asphalt - Part 7: Determination of bulk density of bituminous specimens by gamma rays
Also Known As:
The DIN EN 12697-7 standard outlines the procedure for measuring the bulk density of bituminous specimens using gamma radiation. This method is typically used in conjunction with product standards for bituminous mixtures and must adhere to safety regulations regarding the use of gamma rays.
The standard specifies that the specimens used for testing can either be cylindrical or blocks, which can be prepared in a laboratory or obtained by cutting from existing pavement. The thickness of the specimen body traversed by the radiation should be within the range of 30 mm to 300 mm. However, it's important to note that this method is not applicable to materials that contain slags or have a variable metal content or chemical composition that may affect the absorption of gamma rays.
By utilizing a transmission type gamma radiation test bench, this standard allows for the accurate determination of the bulk density of bituminous specimens. This information can be valuable in assessing the quality and properties of bituminous mixtures used in the construction of roads and pavements.
