本文件规定了使用透射式伽马辐射试验台测量路面混合料体积密度的方法。 该方法适用于实验室制备或从路面切割的圆柱形试样或平行六面体块。已知厚度和质量吸收系数，它是化学成分的函数。辐射穿过的样本体厚度在30 mm到300 mm之间。 该方法不适用于含有金属含量或化学成分可变的熔渣的材料。购买本文件时可获得的所有当前修订均包含在购买本文件中。

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 parallelepipedal 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 is between 30 mm and 300 mm. The method cannot be applied to materials containing slags, with variable metal content or chemical composition.All current amendments available at time of purchase are included with the purchase of this document.
