This document specifies a method for measuring the bulk density of pavement mixtures using a transmission-type gamma radiation test bench.This method applies to cylindrical specimens or blocks, prepared in a laboratory or cut from a pavement, the thickness and the mass absorption coefficient which is a function of the chemical composition are known. The thickness of the specimen body traversed by the radiation shall be between 30 mm and 300 mm.The method cannot be applied to materials containing slags, with variable metal content or chemical composition.NOTE Material containing metal or chemical compositions can affect the absorption of gamma rays.
