Bituminous mixtures - Test methods - Part 40: In situ drainability
This European Standard describes a method to determine the in-situ relative hydraulic conductivity, at specific locations, of a road surfacing that is designed to be permeable. An estimate of the average value for the surfacing is obtained from the mean value of a number of determinations on each section of road.
The test measures the ability to drain water (drainability) achieved in-situ of a surfacing. As such, it can be used as a compliance check to ensure that a permeable surface course has the required properties when it is laid. The test can also be used subsequently to establish the change of drainage ability with time.
For the test to be valid, the surface of the test area should be clean and free from detritus. Measurements can be made when a road is either wet or dry, but not if it is in a frozen state.
Asphalt - Prüfverfahren - Teil 40: In-situ-Durchlässigkeit
Dieses Dokument beschreibt ein Verfahren zur Bestimmung der relativen In-situ-Wasserdurchlässigkeit an festgelegten Punkten einer als wasserdurchlässig ausgelegten Deckschicht. Eine Abschätzung des durchschnittlichen Wertes (der Wasserdurchlässigkeit) der Deckschicht erfolgt durch den Mittelwert aus einer Anzahl von Bestimmungen in jedem Teilstück der betreffenden Straße.
Mit dieser Prüfung wird die Drainagefähigkeit (Durchlässigkeit) der eingebauten Deckschicht gemessen. Als solche kann sie als Nachweis verwendet werden, dass eine durchlässige Deckschicht nach dem Einbau die geforderten Eigenschaften hat. Die Prüfung kann auch später durchgeführt werden, um die Änderung der Durchlässigkeit mit der Zeit zu ermitteln.
Damit die Prüfung gültig ist, sollte die Oberfläche des Prüfbereiches sauber und frei von losen Bestandteilen sein. Die Messungen können entweder bei nasser oder bei trockener Straße, nicht jedoch bei Frost durchgeführt werden.
Mélanges bitumineux - Méthodes d'essai - Partie 40 : Perméabilité en place
Ce document décrit une méthode permettant de déterminer la conductivité hydraulique relative in-situ, à certains endroits spécifiques d’un revêtement routier conçu pour être drainant. Une estimation de la valeur moyenne pour le revêtement est obtenue à partir de la valeur moyenne d’un certain nombre de déterminations sur chaque section de route.
L’essai sert à mesurer in-situ la capacité à drainer l’eau (drainabilité) d’un revêtement. En tant que tel, il peut être utilisé comme contrôle de conformité afin de garantir qu’une couche de surface drainante a les propriétés requises lors de la mise en œuvre. L’essai peut également servir ultérieurement à établir les variations de la capacité drainante avec le temps.
Pour que l’essai soit valable, il est recommandé que la surface de la zone d’essai soit propre et exempte de détritus. Les mesurages peuvent être effectués sur route sèche ou mouillée, mais pas sur route gelée.
