Bituminous mixtures - Test methods for hot mix asphalt - Part 19: Permeability of specimen
This document describes a method for determining the vertical and horizontal permeability of cylindrical specimens of bituminous mixtures. The standard applies to specimens cored out of the road, specimens from laboratory made slabs or laboratory specimens pre¬pared with a compaction device provided the thickness of the specimen is not less than 2,5 times 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 shall be 150 mm diameter.
Asphalt - Prüfverfahren für Heißasphalt - Teil 19: Durchlässigkeit von Probekörper
Dieses Dokument legt ein Verfahren zur Bestimmung der vertikalen und horizontalen Durch¬lässigkeit von zylindrischen Asphalt-Probekörpern fest. Diese Norm gilt für durch Kernbohren aus einer Fahrbahn¬befestigung 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 2,5fache der maximalen Nennkorngröße der im Gemisch verwendeten Gesteins¬körnung 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 Falle muss der Nenndurchmesser 150 mm betragen.
Mélanges bitumineux - Méthodes d'essai pour mélange hydrocarboné à chaud - Partie 19: Perméabilité des éprouvettes
Le présent document décrit une méthode pour déterminer la perméabilité horizontale et verticale d’éprouvettes cylindriques de mélanges bitumineux. Cette norme s’applique à des carottes prélevées dans la chaussée, des éprouvettes extraites de plaques fabriquées en laboratoire avec une table de compactage telle que l’épaisseur de l’éprouvette ne soit pas moins de 2,5 fois la dimension nominale maximale des granulats du mélange. Il convient que le diamètre nominal des éprouvettes soit de 100 mm ou de 150 mm, si la dimension maximale des granulats dépasse 22 mm, le diamètre nominal doit être de 150 mm.

1 Scope This document describes a method for determining the vertical and horizontal permeability of cylindrical specimens of bituminous mixtures. The standard 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 2,5 times 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 shall be 150 mm diameter. 2 Normative references The following referenced document is indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. EN 12697-29, Bituminous mixtures — Test methods for hot mix asphalt — Part 29: Determination of the dimensions of a bituminous specimen. 3 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 Qv or Qh is a calculated measure of the permeability value Kv or Kh. The test is carried out at ambient temperature. NOTE When the void content of the same specimen is determined the relationship between permeability and void content can be established. 4 Vertical permeability 4.1 General In this method, only the water flow in a vertical direction through the specimen is measured. 4.2 Apparatus for vertical permeability Apparatus as shown in Figure 1. The dimensions shall be such as to ensure the water column height is (300 ± 1) mm. The external diameter of the tube shall be greater than the diameter of the specimen by up to 5 mm and the maximum thickness of the tube wall shall be limited to 5 mm. A balance with suitable capacity and capable of weighing to the nearest 0,5 g. 4.3 Procedure 4.3.1 Determine the dimensions of the specimen, to the nearest millimetre, according to EN 12697-29. The thickness shall be greater than 25 % of the diameter and greater than twice the nominal maximum aggregate size of the mixture. 4.3.2 If the specimen is trimmed by saw cutting, it shall be cleaned prior to testing, to prevent restriction of the water flow.
