Bituminous mixtures - Test methods - Part 19: Permeability of specimen

This document specifies a method for determining the vertical and horizontal permeability of cylindrical specimens of bituminous mixtures with interconnecting voids. The document applies to specimens cored out of the road, specimens from laboratory made slabs or laboratory specimens prepared with a compaction device provided the thickness of the specimen is not less than twice the nominal maximum particle size of the aggregate in the mixture. The nominal diameter of specimens should be either 100 mm or 150 mm unless the nominal maximum particle size of the aggregate size exceeds 22 mm, when the nominal diameter is 150 mm.

Asphalt - Prüfverfahren - Teil 19: Durchlässigkeit der Probekörper

Dieses Dokument legt ein Verfahren zur Bestimmung der vertikalen und horizontalen Durchlässigkeit von zylindrischen Asphalt-Probekörpern mit miteinander verbundenen Hohlräumen fest. Dieses Dokument gilt für durch Kernbohren aus einer Fahrbahnbefestigung entnommene Probekörper, für Probekörper aus im Laboratorium hergestellten Platten oder für im Laboratorium mit einer Verdichtungsvorrichtung hergestellte Probekörper, sofern die Dicke des Probekörpers nicht geringer als das Zweifache der maximalen Nennkorngröße der im Gemisch verwendeten Gesteinskörnung ist. Der Nenndurchmesser der Probekörper sollte entweder 100 mm oder 150 mm betragen, es sei denn, die maximale Nennkorngröße der Gesteinskörnung überschreitet 22 mm, in diesem Fall beträgt der Nenndurchmesser 150 mm.

Mélanges bitumineux - Méthodes d'essai - Partie 19 : Perméabilité des éprouvettes

Ce document spécifie une méthode pour déterminer la perméabilité verticale et horizontale d’éprouvettes cylindriques de mélanges bitumineux avec des vides communicants. Ce document s’applique à des carottes prélevées dans la chaussée, à des éprouvettes extraites de plaques fabriquées en laboratoire ou à des éprouvettes de laboratoire préparées avec un dispositif de compactage, à condition que l’épaisseur de l’éprouvette ne soit pas inférieure à deux fois la dimension nominale maximale des granulats du mélange. Il convient que le diamètre nominal des éprouvettes soit égal à 100 mm ou à 150 mm, sauf si la dimension nominale maximale des granulats dépasse 22 mm alors que le diamètre nominal est de 150 mm.

1 Scope

cylindrical specimens of bituminous mixtures with interconnecting voids. The document applies to

specimens cored out of the road, specimens from laboratory made slabs or laboratory specimens

prepared with a compaction device provided the thickness of the specimen is not less than twice the

nominal maximum particle size of the aggregate in the mixture. The nominal diameter of specimens

should be either 100 mm or 150 mm unless the nominal maximum particle size of the aggregate size

exceeds 22 mm, when the nominal diameter is 150 mm.

4 Principle

A column of water with a constant height is applied to a cylindrical specimen and is allowed to

permeate through the specimen for a controlled time in either a vertical or horizontal direction

depending upon the parameter being measured. The resultant flow rate of the water Q or Q is a

v h

calculated measure of the permeability value K or K . The test is carried out at ambient temperature.

v h

NOTE When the void content of the same specimen is determined, the relationship between permeability and

void content can be established.
5 Vertical permeability
5.1 General

In this method, only the water flow in a vertical direction through the specimen is measured.

5.2 Apparatus for vertical permeability

5.2.1 Apparatus as shown in Figure 1. The dimensions shall be such to ensure the water column

height is (300 ± 1) mm. The external diameter of the tube and any fittings shall be such that no water

can flow between the wall of the tube and the specimen when in place; the thickness of the tube shall be

sufficient to ensure it retains its shape but shall not be more than 5 mm.

The external diameter of the tube should generally be greater than the diameter of the specimen by up

to 5 mm.

EN 12697-19:2020 (E)

NOTE A suitable rubber cuff that fits snugly around the tube and sample is one method to ensure that no

water can flow between the two. Another approach that could be used is to attach the plastic tube with duct tape

to the specimen.
