Standard EN SampleBituminous Mixtures: Test Methods for Hot Mix Asphalt - Determination of Bulk Density of Bituminous Specimens by Gamma Rays
Also Known As:
BS EN 12697-7:2014 is a European standard that outlines a method for determining the bulk density of bituminous specimens using gamma rays. This standard is applicable to the measurement of bulk density in pavement mixtures, and it is described in the product standards for bituminous mixtures.
The method outlined in this standard involves using a transmission-type gamma radiation test bench. However, it is important to adhere to the safety regulations applicable to the use of gamma rays. The standard applies to cylindrical specimens or blocks that can be prepared in a laboratory or cut from a pavement. It is necessary to know the thickness and mass absorption coefficient (which is dependent on the chemical composition) of the specimens.
The thickness of the specimen body through which the gamma radiation passes must be in the range of 30 mm to 300 mm. It is important to note that this method is not suitable for materials containing slags, as well as materials with variable metal content or chemical composition that may impact the absorption of gamma rays.
