Bituminous mixtures - Test methods - Part 23: Determination of the indirect tensile strength of bituminous specimens

This draft European Standard specifies a test method for determining the (splitting) indirect tensile strength of cylindrical specimens of bituminous mixtures.
NOTE   Determination of the water sensitivity of bituminous specimens in accordance with EN 12697-12 is based on determination of the indirect tensile strength in accordance with this test method.

Asphalt - Prüfverfahren - Teil 23: Bestimmung der indirekten Zugfestigkeit von Asphalt-Probekörpern

Dieser Europäische Norm-Entwurf legt ein Prüfverfahren zur Bestimmung der indirekten Zugfestigkeit (Spalt-zugfestigkeit) von zylindrischen Asphalt-Probekörpern fest.
ANMERKUNG   Die Bestimmung der Wasserempfindlichkeit von Asphalt-Probekörpern nach EN 12697-12 beruht auf der Bestimmung der indirekten Zugfestigkeit nach dem vorliegenden Prüfverfahren.

Mélanges bitumineux - Méthode d'essais - Partie 23 : Détermination de la résistance à la traction indirecte des éprouvettes bitumineuses

Le présent projet de Norme européenne spécifie une méthode d’essai permettant de déterminer la résistance à la traction indirecte (fendage) d’éprouvettes cylindriques de mélanges bitumineux.
NOTE   La détermination de la sensibilité à l'eau des éprouvettes bitumineuses selon l'EN 12697-12 est fondée sur la détermination de la résistance à la traction indirecte selon la présente méthode d’essai.

Bitumenske zmesi - Preskusne metode - 23. del: Ugotavljanje posredne natezne trdnosti bitumenskih preskušancev

Ta osnutek evropskega standarda določa preskusno metodo za ugotavljanje (ločevanje) posredne natezne trdnosti cilindričnih preskušancev iz bitumenskih mešanic.
OPOMBA: Ugotavljanje občutljivosti bitumenskih preskušancev na vodo v skladu s standardom EN 12697-12 temelji na ugotavljanju posredne natezne trdnosti v skladu s to preskusno metodo.
