摘要

The present study was taken up in two phases. Phase-1 focused on a review of devices pertaining to gradation (ASTM C136) tests. The study identified six optical devices. One of them, Computerize Particle Analyzer (CPA) developed by Haver and Boecker became available for investigation. CPA is a photo-optical device which uses 2-dimensional images for measuring the particle size distribution and shape of all dry bulk materials between 40mincrons and 36mm. 46 aggregate samples (sand sized to 25 mm) comprising of limestone, gravel and slag were collected from various sources in Ohio.
