Unbound and hydraulically bound mixtures - Part 1: Test methods for laboratory reference density and water content - Introduction, general requirements and sampling

This document specifies a number of test methods for the determination of the relationship between the water content and the density of unbound and hydraulically bound mixtures under specified test conditions. The test results provide an estimate of the mixture density that can be achieved and provides a reference parameter for assessing the density of the compacted layer of the mixture.
The test results are used as a basis for specifying requirements for hydraulically bound and unbound mixtures.
The test result also allows a conclusion to be drawn as to the water content at which a mixture can be satisfactorily compacted in order to achieve a given density.

Ungebundene und hydraulisch gebundene Gemische - Teil 1: Laborprüfverfahren für die Trockendichte und den Wassergehalt - Einführung, allgemeine Anforderungen und Probenahme

1   Anwendungsbereich
Dieses Dokument legt eine Anzahl von Verfahren fest, mit denen die Beziehung zwischen dem Wassergehalt und der Dichte ungebundener und hydraulisch gebundener Gemische unter vorgegebenen Prüfbedingungen ermittelt werden kann. Die Prüfergebnisse liefern einen Anhaltswert für die erreichbare Dichte des Gemisches und einen Bezugsparameter zur Beurteilung der Dichte einer verdichteten Schicht des Gemisches.
Die Prüfergebnisse werden als Grundlage für die Festlegung von Anforderungen an hydraulisch gebundene und ungebundene Gemische angewendet.
Die Prüfergebnisse lassen auch erkennen, bei welchem Wassergehalt ein Gemisch sich günstig verdichten lässt, um bestimmte Trockendichten zu erreichen.

Nevezane in hidravlično vezane zmesi - 1. del: Preskusne metode za laboratorijsko referenčno gostoto in vsebnost vode - Uvod, splošne zahteve in vzorčenje

Ta dokument določa število preskusnih metod za določanje razmerja med vsebnostjo vode in gostoto nevezanih in hidravlično vezanih zmesi pod opredeljenimi preskusnimi pogoji. Rezultati preskusa zagotavljajo oceno gostote mešanice, ki jo je mogoče doseči in določa referenčni parameter za ocenjevanje gostote stisnjene plasti zmesi.
Rezultati preskusa se uporabljajo kot osnova za določitev zahtev za nevezane in hidravlično vezane zmesi.
Na podlagi rezultata preskusa je mogoče tudi ugotoviti, pri kateri vsebnosti vode je mogoče zmes zadovoljivo stisniti, da se doseže dana gostota.
