Determination of Fines Produced during Crushing, Handling, and Placement of Aggregates Employed in Roadway Construction

摘要

A three part test procedure was developed to simulate the production of fines during crushing, handling, and placement of roadway aggregates. Results of the test procedure were correlated to a standard aggregate degradation test (the Washington Degradation Test). Records of the fines produced during crushing, handling, and placement in the field were examined with respect to the laboratory test results. The fines produced in the three part procedure were analyzed to determine their nature with respect to contributing to potential frost action in base course aggregates.
