Evaluation/Comparison of Alternative F&E Test Devices for Aggregate Shape Determination

Project No: 76142

Target Completion Date: November 18, 2005 Structures

About the project:

The project proposed to evaluate and compare three devices for characterizing the flatness and/or elongation of coarse aggregates. The three devices include one mechanical device (the proportional caliper) and two digital devices (digital calipers). Multiple tests with each device, as well as test reproduction with different technicians will permit a comparison of the respective devices, and recommendations regarding future procurement and use.
