Use of the Micro-Deval Test for Assessing Fine Aggregate Durability
The Micro-Deval test was evaluated for its suitability in assessing the durability of fine aggregate from Virginia sources. Fine aggregates from 10 sources with known performance histories were tested with the Micro-Deval and several common aggregate quality methods. The Canadian Micro-Deval testing protocol for fine aggregates was followed. The results obtained with the Micro-Deval test showed better precision than those obtained with the conventional aggregate tests. In terms of field performance rating, the Micro-Deval test was able to differentiate between good- and poor-performing aggregates at least 80% of the time and was able to identify differences in quality between similar aggregate types with varying degrees of weathering. The Micro-Deval test is recommended as a quality control tool for fine aggregate assessment to supplement the current measures of aggregate quality. After sufficient data have been gathered and compared with data regarding field performance, it may be possible to replace the existing soundness or freeze–thaw tests with the Micro-Deval test.
