An Evaluation of the Calderon Test, HR-80, 1963

As a result of Chang's studies, Calderon's developments, and the need for a new test procedure to determine specific physical properties of an asphalt concrete, the Iowa Highway Research Board sponsored a research project to investigate the correlation of results of the Calderon Test with the Iowa Stability Test and the Marshall and Hveem stability tests using Iowa Type A asphaltic concrete. The project was assigned to the Bituminous. Research Laboratory of Iowa State University as Project HR 80, the. Iowa Highway Research Board, and Project 442-S of the Engineering Experiment Station.
