Coarse Aggregate Angularity Apparatus measures the uncompacted void content of coarse aggregate. The test method is recommended to evaluate aggregates for Hot-Mix Asphalt (HMA) pavement.
Test Method :
Gradation and void content data provide an indication of angularity, sphericity, and surface texture, which are 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.
Construction :
The hopper, stand, and measure are made of stainless steel, and a locator pin and circle on the bottom plate of the stand ensure the measure is positioned correctly beneath the hopper.
Supply Includes :
Coarse Aggregate Angularity Apparatus consists of stainless steel measure, strike-off bar, and glass plate for calibration.
Ordering Information :
Steel material handling pan should be ordered separately.
