Bituminous mixtures - Test methods - Part 7: Determination of the bulk density of bituminous specimens by gamma rays
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.
Asphalt - Prüfverfahren - Teil 7: Bestimmung der Raumdichte von Asphalt-Probekörpern mit Gammastrahlen
Dieses Dokument beschreibt ein Verfahren, mit dem die Raumdichte von Asphaltgemischen für Fahrbahnbeläge gemessen wird, wenn eine Durchstrahlungseinrichtung mit Gammastrahlung verwendet wird.
Dieses Verfahren gilt für zylindrische oder blockförmige, im Labor hergestellte oder einem Fahrbahnbelag entnommene Probekörper, deren Dicke und von der chemischen Zusammensetzung abhängiger Massenabsorptionskoeffizient bekannt sind. Die Dicke des Probekörpers, der bei der Messung von Gammastrahlen durchdrungen wird, muss zwischen 30 mm und 300 mm betragen.
Dieses Verfahren kann nicht auf Materialien angewendet werden, die Schlacken enthalten oder über unterschiedliche Metallgehalte oder unterschiedliche chemische Zusammensetzungen verfügen.
ANMERKUNG Materialien mit Metallgehalten oder mit chemischer Zusammensetzung können die Absorption der Gammastrahlen verändern.
Mélanges bitumineux - Méthodes d’essai - Partie 7 : Détermination de la masse volumique apparente des éprouvettes bitumineuses par les rayons gamma
Le présent document décrit une méthode de mesure de la masse volumique apparente des matériaux de chaussée au moyen d’un banc d’essai à rayons gamma par transmission.
Cette méthode s’applique à des éprouvettes cylindriques ou blocs parallélépipédiques, préparés en laboratoire ou découpés dans une chaussée. L’épaisseur et le coefficient d’absorption massique qui est fonction de la composition chimique sont connus. L’épaisseur du corps d’éprouvette traversé par le rayonnement doit être comprise entre 30 mm et 300 mm.
La méthode ne peut être appliquée à des matériaux contenant des laitiers présentant une teneur en métal ou une composition chimique variable.
NOTE Les matériaux contenant du métal ou présentant des compositions chimiques variables peuvent affecter l’absorption des rayons gamma.
Bitumenske zmesi - Preskusne metode - 7. del: Ugotavljanje gostote bitumenskih preskušancev z žarki gama
Ta dokument določa metodo za merjenje gostote vozišč s preskusno mizo za oddajanje žarkov gama.
Ta metoda se uporablja 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 vsebnostjo kovin ali kemijsko sestavo.
OPOMBA: Snovi z vsebnostjo kovin ali kemijsko sestavo lahko vplivajo na absorpcijo žarkov gama.

3.1
precision
closeness of agreement between independent test results obtained under stipulated conditions
Note 1 to entry: Precision depends only on the distribution of random errors and does not relate to the true value
or the specified value.
Note 2 to entry: The measure of precision is usually expressed in terms of imprecision and computed as a
standard deviation of the test results. Less precision is indicated by a larger standard deviation.
Note 3 to entry: “Independent test results” means results obtained in a manner not influenced by any previous
result on the same or similar test sample. Quantitative measures of precision depend critically on the stipulated
conditions. Repeatability and reproducibility conditions are particular sets of extreme conditions.
