A PROTOTYPE LASER SCANNER FOR CHARACTERIZING SIZE AND SHAPE PARAMETERS IN AGGREGATES

The Laser-based Aggregate Scanning System (LASS) is being developed at The University of Texas at Austin to rapidly characterize various properties of construction aggregates. For the determination of shape and size parameters for aggregates, "virtual proportional caliper" and "virtual sieve" concepts are introduced, where 3D data captured on each particle are rotated about different axes to find elongation and flatness ratios, and the smallest mesh opening size through which the particle can pass. Comparisons between manual measurements and the results from the LASS show good agreement.
