Bituminous mixtures - Test methods - Part 52: Conditioning to address oxidative ageing
|Publication Date:||1 July 2015|
|ICS Code (Road construction materials):||93.080.20|
This European Standard describes two sets of procedures for conditioning of bituminous mixtures in terms of oxidative ageing. Procedures A.1 and A.2 can be applied on loose bituminous mixture before compaction of specimens, procedures B.1 and B.2 on compacted specimens. Material conditioned by this European Standard can be used for further testing to assess the effect of oxidative ageing on characteristics of bituminous mixtures and thus on their durability and recyclability. Alternatively, binder can be extracted from conditioned mixture to assess the effect of oxidative ageing on binder characteristics taking into account potential effects of mineral aggregates on ageing.
This European Standard is applicable to bituminous mixtures manufactured in the laboratory or in a mixing plant. Procedures B.1 and B.2 is applicable to specimens from laboratory production or cores taken from the field.
