Earthworks - Geotechnical laboratory tests - Part 1: Degradability test standard

This document defines the principle and the methods for the determination of the "degradability coefficient" of rocky material.
The degradability coefficient IDG distinguishes the behaviour of certain rocky material and is used to show the change in the geotechnical characteristics (particle size, clay content, plasticity, etc.) in relation to the characteristics seen immediately following excavation.
Changes in the particle size occur due to the combined action of climatic or geohydrological elements (frost, soaking-drying cycles) and mechanical stress to which it is subjected. In the case of degradable rocky material, this leads to a fairly significant and continuous reduction in the mechanical and geometric characteristics of the works in which they are used.
The two methods developed in this document for the determination of IDG are not equivalent, so any result obtained by this document can refer to the method used.

Erdarbeiten - Geotechnische Laborversuche - Teil 1: Prüfung der Abbaubarkeit

Dieses Dokument definiert die Grundlagen und die Verfahren zur Bestimmung des "Abbaubarkeits-koeffizienten" von Felsmaterial.
Der Abbaubarkeitskoeffizient IDG unterscheidet das Verhalten bestimmter Felsmaterialien und wird ver-wendet, um die Änderungen der geotechnischen Merkmale (Korngröße, Tongehalt, Plastizität usw.) im Verhältnis zu den Merkmalen darzustellen, wie sie unmittelbar nach dem Lösen erkennbar sind.
Änderungen der Korngröße treten aufgrund der kombinierten Wirkung von klimatischen und geohydro-logischen Elementen (Frost, Wässerungs-Trocknungs-Zyklen) und der mechanischen Belastung auf, denen das Material ausgesetzt wird. Bei veränderlichen Felsmaterialien führt dies zu einer recht signifikanten und kontinuierlichen Herabsetzung der mechanischen und geometrischen Merkmale der Arbeiten, bei denen diese eingesetzt werden.
Die beiden in diesem Dokument entwickelten Verfahren für die Bestimmung von IDG sind nicht äquivalent, so dass aufgrund dieses Dokuments erhaltene Ergebnisse auf das verwendete Verfahren Bezug nehmen können.

Terrassements - Essais géotechniques en laboratoire - Partie 1 : Essai de dégradabilité

Le présent document définit le principe et les méthodes de détermination du « coefficient de dégradabilité » d’un matériau rocheux.
Le coefficient de dégradabilité IDG sert à distinguer le comportement de certains matériaux rocheux et est utilisé pour apprécier l’évolution des caractéristiques géotechniques (granulométrie, teneur en argile, plasticité, etc.) par rapport aux caractéristiques observées immédiatement après l’excavation.
Des modifications de la granulométrie se produisent sous l’action combinée des éléments climatiques ou hydrogéologiques (gel, cycles d’humidification-séchage) et des contraintes mécaniques auxquelles ils sont soumis. Dans le cas de matériaux rocheux dégradables, cela conduit à une détérioration relativement importante et continue des caractéristiques mécaniques et géométriques des ouvrages dans lesquels ils sont utilisés.
Les deux méthodes décrites dans le présent document pour la détermination du coefficient IDG n’étant pas équivalentes, les résultats obtenus à partir de ce document se réfèrent à la méthode utilisée.

Zemeljska dela - Geotehnični laboratorijski preskusi - 1. del: Preskus razgradljivosti

Ta dokument določa načelo in metode za določanje »koeficienta razgradljivosti« kamninskega materiala.
Koeficient razgradljivosti IDG označuje obnašanje določenega kamninskega materiala in se uporablja za prikaz sprememb geotehničnih lastnosti (velikost delcev, vsebnost gline, plastičnost itd.) glede na lastnosti, zaznane takoj po izkopu.
Velikost delcev se spremeni zaradi skupnega delovanja podnebnih oziroma geohidroloških dejavnikov (zmrzal, cikli močenja in sušenja) in mehanskih obremenitev, katerim so izpostavljeni. To pa pri razgradljivem kamninskem materialu povzroči znatno in stalno zmanjševanje mehanskih ter geometrijskih lastnosti proizvodov, v katerih se uporabljajo.
Metodi za določanje IDG, oblikovani v tem dokumentu, nista enakovredni, zato se lahko na uporabo metode sklicuje vsak rezultat, pridobljen na podlagi tega dokumenta.
