Round robin bitumen : viscosity (English)
Abstract [sv]

En ringanalys har genomförts av sju olika laboratorier i Sverige för fyra olika bitumenkvalitéer, två penetrationsbitumen och två mjukbitumen. Syftet med ringanalysen var att jämföra viskositetsmätningar med kapillärer mot den nya varianten med rotationsviskosimeter. Utöver dessa metoder analyserades även åldringsegenskaper vilket senare inte utvärderades. Mycket data samlades in från olika varianter på dessa analyser och fokus har sedan legat på att utvärdera data från SS-EN 13302, SS-EN 12595 och SS-EN 12596 som var det huvudsakliga syftet med ringanalysen. Utvärderingen har handlat om att jämföra reproducerbarheten, R, för de olika metoderna vid denna ringanalys med standardernas angivna precisionsmått. För metoden SS-EN 13302 var ringanalysens spridning generellt mindre än metodens precisionsmått medan det för SS-EN 12595 och SS-EN 12596 generellt var större.

Abstract [en]

A round robin was carried out by seven different laboratories in Sweden for four different types of bituminous binders, two harder bitumen and two soft bitumen. The purpose of the round robin test was to compare the viscosity methods using capillaries against the new variant with a rotating spindle viscometer. Apart from these methods the aging characteristics was also tested but later not evaluated. Much data were collected from different variations on these analyzes and the focus has been on evaluating data from EN 13302, EN 12595 and EN 12596, which was the main purpose of the round robin. The evaluation has focused on the reproducibility for the various methods compared with the precision in the different standards. The variation in the result for the method SS-EN 13302 was generally lower in this round robin test compared to the precision in the standard while the variation for the SS-EN 12595 and SS-EN 12596 generally was higher.
