CHARACTERIZATION OF MINERAL FILLERS

HET KARAKTERISEREN VAN VULSTOFFEN

Characterization of mineral filler based on its main function in bituminous mixtures is discussed. Several test methods were examined in order to assess their suitability for the evaluation of filler quality: determination of (1) voids per cent according to Rigden, (2) apparent density in benzene, (3) bitumen absorption number (Van der Baan's ratio), (4) specific surface. A "bitumen absorption number by volume" is proposed as a criterion for quality. The fineness of the filler could be used as an additional criterion. /TRRL/
