Bituminous mixtures - Test methods for hot mix asphalt - Part 7: Determination of bulk density of bituminous specimens by gamma rays
EN 12697-7 specifies a method for measuring the bulk density of pavement mixtures using a transmission-type gamma radiation test bench. The applicability of this European Standard is described in the product standards for bituminous mixtures. The safety regulations applicable to the use of gamma rays should be applied. This European Standard 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 which may affect the absorption of gamma rays.
Asphalt - Prüfverfahren für Heißasphalt - Teil 7: Bestimmung der Raumdichte von Asphalt-Probekörpern mit Gamma-Strahlen
Diese Europäische Norm beschreibt ein Verfahren, mit dem die Raumdichte von Asphaltgemischen für Fahrbahnbeläge gemessen werden kann, wenn eine Durchstrahlungseinrichtung mit Gamma-Strahlung verwendet wird.
Die Anwendung dieser Europäischen Norm ist in den Produktnormen für Asphalt beschrieben.
Die Sicherheitsvorschriften für den Umgang mit Gamma-Strahlenquellen sollten beachtet werden.
Diese Europäische Norm gilt für zylindrische oder blockförmige Probekörper, die im Labor hergestellt oder einem Fahrbahnbelag entnommen werden, deren Masse und von der chemischen Zusammensetzung abhän-giger Massenabsorptionskoeffizient bekannt sind. Die Dicke des Probekörpers, der bei der Messung von Gamma-Strahlen durchdrungen wird, muss zwischen 30 mm und 300 mm betragen. Dieses Verfahren kann nicht auf Materialien angewendet werden, die Schlacken mit unterschiedlichen Metallgehalten oder che¬mischer Zusammensetzung enthalten und die Absorption der Gamma-Strahlen verändern könnten.

Bitumenske zmesi - Preskusne metode za vroče asfaltne zmesi - 7. del: Ugotavljanje gostote bitumenskih preskušancev z žarki gama
Standard EN 12697-7 določa metodo za merjenje gostote vozišč s preskusno mizo za oddajanje žarkov gama. Uporabnost tega evropskega standarda je opisana v standardih za izdelke za bitumenske zmesi. Upoštevalo naj bi se varnostne predpise, ki veljajo za uporabo gama žarkov. Ta evropski standard velja za valjaste preskušance ali bloke, pripravljene v laboratoriju, ali izrezane iz vozišč, katerih debelina in koeficient absorpcije mase, kar je funkcija kemične sestave, sta znana. Debelina vzorca telesa, skozi katerega poteka sevanje, mora biti med 30 mm in 300 mm. Metode ni mogoče uporabljati za snovi, ki vsebujejo žlindre ali s spremenljivo kovinsko vsebino ali kemijsko sestavo, ki lahko vplivajo na absorpcijo žarkov gama.
