Bitumenske zmesi - Preskusne metode - 15. del: Ugotavljanje občutljivosti na segregacijo
Ta dokument določa preskusno metodo za ugotavljanje kakovosti mešanja in nagnjenosti k segregaciji v sestavi vročih bitumenskih zmesi. Ta preskusna metoda je primerna za načrtovanje zmesi in informiranje naročnikov.
OPOMBA: Ta preskusna metoda temelji na vročih bitumenskih zmeseh. Pri drugih vrstah bitumenskih zmesi (npr. bitumenski beton z bitumensko emulzijo) ni izkušenj.

Introduction
The homogeneity of the quality level of a bituminous pavement is among others determined by the
homogeneity of the composition of the bituminous mixtures applied. The homogeneity of a bituminous
mixture in the pavement is influenced by the mixing quality during production and by its segregation
sensitivity during handling. The latter is influenced by the mixture composition in terms of type and amount
of aggregate and binder. Some segregation is inherent to the nature of bituminous materials. Undue
segregation is caused by e.g. not appropriate mixing, improper loading of the hopper, lorry or finisher.
This test method provides useful information on the homogeneity quality of a bituminous mixture. The test
data provide information on the efficacy of the mixing procedure and on the sensitivity of the mixture for
segregation in its composition during the handling so that appropriate measures can be taken to minimize
such segregation where considered necessary.
1 Scope
This document specifies a test method for the determination of the mixing quality and the tendency of
segregation in composition of bituminous mixtures. This test method is considered suitable for mix-design
purposes and for client information.
NOTE This test method is based on hot bituminous mixtures. There is no experience for other types of bituminous
mixtures, e.g. asphalt concrete with bituminous emulsions.
