Geotechnical investigation and testing - Laboratory testing of soil - Part 12: Determination of liquid and plastic limits - Amendment 1 (ISO 17892-12:2018/Amd 1:2021)
This document specifies methods for the determination of the liquid and plastic limits of a soil. These comprise two of the Atterberg limits for soils.
The liquid limit is the water content at which a soil changes from the liquid to the plastic state.
This document describes the determination of the liquid limit of a specimen of natural soil, or of a specimen of soil from which material larger than about 0,4 mm has been removed. This document describes two methods: the fall cone method and the Casagrande method.
NOTE The fall cone method in this document should not be confused with that of ISO 17892‑6.
The plastic limit of a soil is the water content at which a soil ceases to be plastic when dried further.
The determination of the plastic limit is normally made in conjunction with the determination of the liquid limit. It is recognized that the results of the test are subject to the judgement of the operator, and that some variability in results will occur.
Geotechnische Erkundung und Untersuchung - Laborversuche an Bodenproben - Teil 12: Bestimmung der Fließ- und Ausrollgrenzen - Änderung 1 (ISO 17892-12:2018/Amd 1:2021)
Diese Internationale Norm legt Verfahren zur Bestimmung der Fließ- und Ausrollgrenze von durchmischten Böden fest. Dies umfasst zwei der Zustandsgrenzen für Böden nach Atterberg.
Die Fließgrenze ist der Wassergehalt, bei dem der Boden vom flüssigen in den plastischen Zustand übergeht.
Dieses Dokument beschreibt die Bestimmung der Fließgrenze an einer Probe von natürlichem Boden oder einer Bodenprobe, bei denen die Körner mit einem Korndurchmesser größer als 0,4 mm entfernt wurden. Dieses Dokument beschreibt zwei Methoden: Die Fallkegelmethode und die Methode von Casagrande.
ANMERKUNG Die Fallkegelmethode in dieser Norm sollte nicht mit der in ISO 19892 6 verwendeten verwechselt werden.
Die Ausrollgrenze ist der Wassergehalt, bei dem der Boden bei weiterer Trocknung aufhört, plastisch zu sein.
Die Bestimmung der Ausrollgrenze erfolgt normalerweise in Verbindung mit der Bestimmung der Fließgrenze. Es wird anerkannt, dass die Ergebnisse der Prüfung dem Urteil des Prüfers unterliegen und dass in den Ergebnissen eine gewisse Variabilität auftreten wird.
Reconnaissance et essais géotechniques - Essais de laboratoire sur les sols - Partie 12: Détermination des limites de liquidité et de plasticité - Amendement 1 (ISO 17892-12:2018/Amd 1:2021)
Le présent document spécifie les méthodes de détermination des limites de liquidité et de plasticité d'un sol. Celles-ci constituent deux des limites d'Atterberg applicables aux sols.
La limite de liquidité est la teneur en eau à laquelle un sol passe de l'état liquide à l'état plastique.
Le présent document décrit la détermination de la limite de liquidité d'un échantillon de sol naturel, ou d'un échantillon de sol duquel les matériaux de dimension supérieure à 0,4 mm ont été retirés. Ce document décrit deux méthodes: la méthode du cône tombant et la méthode de Casagrande.
NOTE La méthode du cône tombant dans ce document ne devrait pas être confondue avec celle de la norme ISO 17892‑6.
La limite de plasticité d'un sol est la teneur en eau à laquelle ce sol cesse d'être plastique lorsque l'on continue à le sécher.
La détermination de la limite de plasticité est normalement faite en parallèle avec celle de la limite de liquidité. Il est reconnu que les résultats de l'essai sont sujets à l'appréciation de l'opérateur, et qu'une certaine dispersion des résultats pourra se produire.
