Aggregate Angularity & Elongation

For more information read our blog Characteristics of Aggregates: Shape, Size, and Specific Gravity.

• Void Content measures the angularity, sphericity, and surface texture of fine and coarse aggregates.
• Proportional Calipers are efficient devices that quickly determine percentages of elongated and flat particles in coarse aggregate fractions.
• Flakiness & Elongation of Aggregates is measured using a thickness gauge and a length gauge to hand-try particles when determining the flakiness index and elongation index.
• Ballast Ratio Gauges provide quick and precise shape determinations of railway ballast for use in calculating flatness and elongation ratio.
