WX-2000 Fine Aggregate Angularity Apparatus

This instrument is used to measure the clearance rate of a certain amount of fine aggregates passing through a standard funnel and loaded into a standard container, which is called the angularity of fine aggregates, expressed as a percentage. It is suitable for measuring the angularity of fine aggregates used for pavement such as natural sand, artificial sand, stone chips, etc., to predict the influence of fine aggregates on the internal friction angle and resistance to flow deformation of asphalt mixtures. The upper part is a metal or plastic cylindrical volumetric flask with a volume of 250mL, and the bottom is a metal inverted cone funnel with a height of 38mm, the angle is 60°±4°,…
