Bituminous mixtures - Test methods - Part 20: Indentation using cube or Marshall specimens

This document specifies a test method for determining the depth of indentation of mastic asphalt and other asphalt, when force is applied to them via a cylindrical indentor pin with a circular flat-ended base. This document applies to aggregates of maximum nominal size less than or equal to 16 mm.

Asphalt - Prüfverfahren - Teil 20: Eindringversuch an Würfeln oder Marshall-Probekörpern

Dieses Dokument legt ein Prüfverfahren zur Bestimmung der Eindringtiefe von Gussasphalt und anderer Asphaltarten bei Beanspruchung mit einem zylindrischen Stempel mit kreisförmiger ebener Grundfläche fest. Dieses Dokument gilt für Gesteinskörnungen mit einer maximalen Nenngröße gleich oder kleiner als 16 mm.

Mélanges bitumineux - Méthodes d’essai - Partie 20 : Essai d'indentation de cubes ou éprouvettes Marshall

Ce document spécifie une méthode d’essai pour déterminer la profondeur d’indentation d’un asphalte coulé et d’autres types d’enrobés sous l’effet d’une force exercée par l’intermédiaire d’un poinçon cylindrique à embout plat circulaire. Ce document s’applique à des granulats dont la granulométrie nominale maximale est inférieure ou égale à 16 mm.
