Earthworks - Soil treatment tests - Part 1: pH-test for determination of the lime requirement of soils for stabilization (Lime Fixation Point LFP, Lime Modification Optimum LMO)

This document describes the reference method for the determination of the lime fixation point (LFP) in soil treatment for earthworks.
The test consists in measuring the lowest quantity of lime to be added in a soil suspension in water that will result in a pH value of the soil-lime mix suspension of 12,4, measured at 25 °C ± 1 °C.
This test method cannot be used to provide information about soil reactivity with lime, or other performance values (mechanical characteristics of soil-lime mixes) applicable for improvement or stabilization purposes. Those performance tests will be conducted in a laboratory from a specific study, the lime dosage to be applied being indicated from this method.

Erdarbeiten - Prüfungen zur Bodenbehandlung - Teil 1: pH Test zur Bestimmung des Kalkbedarfs von Böden zur Stabilisierung (Bestimmung des minimalen Kalkgehalts LFP und des optimalen Kalkgehalts LMO)

Dieses Dokument beschreibt das Referenzverfahren zur Bestimmung des minimalen Kalkgehalts (en: lime fixation point, LFP) bei der Bodenbehandlung für Erdarbeiten.
Die Prüfung besteht aus der Messung der geringsten Kalkmenge, die in eine wässrige Bodensuspension hinzugegeben werden muss, damit eine Boden-Kalk-Mischung mit einem pH Wert von 12,4, gemessen bei 25 °C ± 1 °C, entsteht.
Dieses Prüfverfahren kann nicht dazu verwendet werden, um Informationen über die Bodenreaktivität mit Kalk oder anderen Leistungswerten (mechanische Merkmale von Boden-Kalk-Gemischen) für Verbesserungs- oder Stabilisierungszwecke zu gewinnen. Diese Leistungsprüfungen werden unter Laborbedingungen mit einer spezifischen Studie durchgeführt, woraus die ermittelte Kalkdosierung durch dieses Verfahren angegeben wird.

Terrassements - Essais de traitement de sol - Partie 1 : Essai pH pour la détermination du besoin en chaux pour la stabilisation des sols (Point de fixation de la chaux LFP, Optimum de modification de la chaux LMO)

Ce document décrit la méthode de référence pour la détermination du point de fixation de la chaux (LFP) dans le traitement des sols pour les travaux de terrassement.
L'essai consiste à mesurer la plus petite quantité de chaux à ajouter dans une suspension de sol dans l'eau qui permettra d'obtenir une valeur de pH de la suspension du mélange sol-chaux de 12,4, mesuré à 25 °C ± 1 °C.
Cette méthode d'essai ne peut être utilisée pour fournir des informations sur la réactivité du sol avec la chaux, ou d'autres valeurs de performance (caractéristiques mécaniques des mélanges sol-chaux) applicables à des fins d'amélioration ou de stabilisation. Ces essais de performance seront réalisés en laboratoire à partir d'une étude spécifique, le dosage de la chaux à appliquer étant indiqué à partir de cette méthode.

Zemeljska dela - Preskusi obdelave zemljin - 1. del: pH test za določanje vsebnosti apna v zemljini pri stabilizaciji (točka vezave apna LFP, optimum apnene stabilizacije LMO)

Ta dokument opisuje referenčno metodo za določanje točke vezave apna (LFP) pri obdelavi zemljin za zemeljska dela.
Preskus vključuje merjenje najmanjše količine apna, ki jo je treba dodati v suspenziji zemljine v vodi, da dobimo vrednost pH suspenzije mešanice zemljine in apna, ki znaša 12,4, merjeno pri 25 +/– 1 °C.
