Bituminous mixtures - Test methods - Part 6: Determination of bulk density of bituminous specimens

This European Standard describes test methods for determining the bulk density of a compacted bituminous specimen. The test methods are intended for use with laboratory compacted specimens or specimens from the pavement after placement and compacting, either by coring or sawing.
This European Standard describes the following four procedures, the choice of which is used being dependent on the estimated content and accessibility of voids in the specimen:
1. bulk density — dry (for specimens with a very closed surface);
2. bulk density — saturated surface dry (SSD) (for specimens with a closed surface);
3. bulk density — sealed specimen (for specimens with an open or coarse surface);
4. bulk density by dimensions (for specimens with a regular surface and with geometric shapes, i.e. squares, rectangles, cylinders, etc.).
NOTE Annex A (informative) gives general guidance on selecting the appropriate procedure.

Asphalt - Prüfverfahren - Teil 6: Bestimmung der Raumdichte von Asphalt-Probekörpern

Dieses Dokument legt Prüfverfahren zur Bestimmung der Raumdichte von verdichteten Asphalt Probekörpern fest. Diese Prüfverfahren sind für die Anwendung auf im Labor verdichtete Probekörper oder aus Bohrkernen oder durch Schneiden hergestellte Probekörper vorgesehen, die zuvor einer Fahrbahndecke nach deren Einbau und Verdichtung entnommen wurden.
Dieses Dokument legt die folgenden vier Verfahren fest, wobei die Entscheidung, welches von diesen anzuwenden ist, vom geschätzten Hohlraumgehalt und von der Zugänglichkeit der Hohlräume im Probekörper abhängt:
a)   Raumdichte - trocken (für Probekörper mit einer sehr dichten Oberfläche);
b)   Raumdichte - gesättigte Oberfläche trocken (en: Saturated Surface Dry (SSD)) (für Probekörper mit einer dichten Oberfläche);
c)   Raumdichte - umhüllter Probekörper (für Probekörper mit einer offenen oder rauen Oberfläche);
d)   Raumdichte durch Ausmessen (für Probekörper mit einer regelmäßigen Oberfläche und geometrischen Formen, z. B. Quadrate, Rechtecke, Zylinder usw.).
ANMERKUNG   Anhang A (informativ) enthält allgemeine Hinweise zur Auswahl des zutreffenden Prüfverfahrens.

Matériaux enrobés - Méthodes d'essai - Partie 6 : Détermination de la masse volumique apparente des éprouvettes bitumineuses

Ce document décrit les méthodes d’essai pour la détermination de la masse volumique apparente de corps d’épreuve bitumineux après compactage. Les méthodes d’essai sont applicables à des éprouvettes compactées en laboratoire ou à des corps d’épreuve prélevés par carottage ou sciage dans la chaussée après mise en œuvre et compactage.
Ce document décrit quatre modes opératoires ci-après, le choix de chacun d’entre eux dépendant du volume de vides estimé et de leur degré d’interconnexion dans l’éprouvette :
a) masse volumique apparente — sèche (pour les éprouvettes présentant une surface très fermée) ;
b) masse volumique apparente — surface saturée sèche (SSS) (pour les éprouvettes présentant une surface fermée) ;
c) masse volumique apparente — éprouvette étanchée (pour les éprouvettes présentant une surface ouverte ou grossière) ;
d) masse volumique apparente géométrique (pour les éprouvettes présentant une surface régulière et des faces de formes géométriques carrées, rectangulaires, cylindriques, etc.).
NOTE L’Annexe A (informative) donne des indications générales sur le choix du mode opératoire approprié.

4 Principle

The bulk density of an intact compacted bituminous specimen is determined from the mass of the

specimen and its volume. The mass of the specimen is obtained by weighing the dry specimen in air.

For the first three procedures, the volume of the specimen is obtained from its mass in air and its mass

in water. In the dry procedure, the mass in water is determined without pre-treatment. In the SSD-

procedure, the specimen is first saturated with water, after which its surface is blotted dry with a damp

Chamois. In the sealed specimen procedure, the specimen is sealed before immersion in water to

prevent access of water to the voids in the specimen. In the fourth procedure, by dimensions, the

volume of the specimen is obtained by measurement of the dimensions.
5 Materials
5.1 General

Calculate the density of water at the test temperature in megagram per cubic metre (Mg/m ) to the

nearest 0,000 1 Mg/m as follows:
 
7,,59×−t 5 32× t
(1)
ρ 1,000 252 05+ 
 6 
 
where
t is the temperature of the water, in degrees Celsius (°C);

ρ is the density of the water at test temperature, in megagram per cubic metre (Mg/m ).

5.2 Additional materials for the sealed specimen procedure

Material to seal the specimen, in such a way, that inclusion of voids (being no part of the specimen)

between seal and specimen is prevented. The density of the sealing material at test temperature shall be

known to the nearest 0,010 Mg/m .

The material used can be paraffin wax, shrinkage foil, latex emulsion etc. The procedure to apply such

materials should be such that the specimen is not damaged. It is very important that the seal exactly

covers the specimen including the voids which technologically form part of its volume: when applying

the seal penetration of the internal voids belonging to the material is prevented, as well as inclusion of

extra voids between seal and specimen or in seal folds.
6 Apparatus
6.1 General

6.1.1 Balance, with sufficient capacity for weighing the specimen in air and under water (e.g. via a

wire basket, the mass and water displacement of which are taken into account by taring), with an

accuracy of at least 0,1 g for masses up to 5 kg, and 1 g for masses over 5 kg.
6.2 Additional apparatus for the dry, SSD and sealed specimen procedures

6.2.1 Water-bath, maintained at a uniform temperature within ± 1,0 °C in the vicinity of the test

specimen(s).

It shall be provided with a grid to ensure the water circulation around the test specimen. The bath shall

have a capacity of at least three times that
