Bituminous mixtures. Test methods for hot mix asphalt. Part 7: Determination of bulk density of bituminous specimens by gamma rays
This standard defines a method for measuring the bulk density of pavement materials using a transmission-type gamma radiation test bench. This standard applies to specimens or core samples, the thickness of which is known as well as the mass absorption coefficient which is a function of the chemical composition. The thickness of the specimen body traversed by the radiation shall be between 3 and 30 cm. The method cannot be applied to materials containing slags, with variable metal conten, affecting the absorption of gamma rays.
