A SIMPLE METHOD FOR DETERMINING THE SURFACE AREA OF FINE AGGREGATES AND FILLERS IN BITUMINOUS MIXTURES

摘要: This paper proposes a simple method which does not involve an operator to visually determine some shape factor. Only the gradation curves of fine aggregate and filler, their apparent specific gravity are considered. A factor or "fudge" is used. demonstrated with five fillers for surface area was measured independently according ASTM C 204. The tested were: limestone, hydrated lime, glass beads, dolomite, basalt. Sands were also evaluated using method. results indicate that accurate. For covering abstract see IRRD 858225.
