Unbound and hydraulically bound mixtures - Part 47: Test method for the determination of California bearing ratio, immediate bearing index and linear swelling
The standard specifies the method for the laboratory determination of the California bearing ratio (CBR) and immediate bearing index (IBI). The standard describes the principle of the tests, the apparatus required, the preparation of the test specimens, the curing of the specimens if required, the testing of the specimens, and the expression and reporting of the results. The preparation of the test specimens for CBR and IBI determination is by dynamic compaction using Proctor or modified Proctor compactive effort as specified in prEN 00227411.
Ungebundene und hydraulisch gebundene Gemische - Teil 47: Prüfverfahren zur Bestimmung des CBR-Wertes (California bearing ratio), des direkten Tragindex (IBI) und des linearen Schwellwertes
Diese Europäische Norm legt Laborprüfverfahren zur Bestimmung des Kalifornischen Tragfähigkeitswertes und des direkten Tragindex fest.
Die Prüfungen sind für den Teil des Gemisches geeignet, dessen maximale Korngröße 22,4 mm beträgt.
Für den Fall, dass Probekörper während des Aushärtens in Wasser eingelagert werden sollen, enthält diese Europäische Norm auch die vor der Bestimmung des Kalifornischen Tragfähigkeitswertes vorzunehmende Bestimmung der vertikalen Quellung der Probekörper.
Mélanges traités et mélanges non traités aux liants hydrauliques - Partie 47: Méthode d'essai pour la détermination de l'indice portant Californien (CBR), de l'indice de portance immédiate (IPI) et du gonflement
La présente Norme européenne spécifie une méthode de détermination en laboratoire de l'indice portant Californien et de l'indice de portance immédiate.
Les essais conviennent aux parties de mélanges dont la dimension maximale des grains est de 22,4 mm.
Lorsqu'une conservation de l'éprouvette en immersion est requise, cette Norme européenne comprend également la détermination du gonflement vertical avant la détermination de l'indice portant Californien.
