Coarse Aggregate Angularity Apparatus
Coarse Aggregate Angularity Apparatus measures the uncompacted void content of coarse aggregate. The testing apparatus is recommended to evaluate aggregates for Hot-Mix Asphalt (HMA) pavement. Gradation and void content data provide an indication of angularity, sphericity, and surface texture that can be related to permanent deformation and fatigue cracking of asphalt.
Aggregate is allowed to free fall from the hopper into a cylindrical measure. Excess heaped aggregate is struck off using the included bar, the mass is measured, and void content is computed. The hopper, stand, and measure is stainless steel and a locator pin and circle on the bottom plate of the stand make it easy to center the measure below the hopper.
Coarse Aggregate Angularity Apparatus consist of Stainless Steel Measure, Strike-off Bar and Glass Plate for calibration.
Steel Material Handling Pan should be ordered separately.

What is Coarse Aggregate Angularity Apparatus?
Coarse Aggregate Angularity Test determines by visual inspection the amount (as a percent by weight) of coarse aggregate particles having fractured faces. The percentage of particles having fractured faces is then compared to the specification requirements.
