Methods to Determine Long-Term Durability of Wisconsin Aggregates.

摘要

The objective of this research was to: Assess whether the outcomes of the Micro-Deval and the unconfined freeze-thaw tests are statistically correlated with current standard aggregate tests that are being performed routinely by WisDOT; Determine the statistical relationships between the existing standard tests and the Micro-Deval test, if a reasonably accurate relationship can be developed; Provide statistical information on the various results included in the Wisconsin database of aggregate tests; and Determine the effects of unconfined freeze-thaw and sodium sulfate soundness tests on the internal void structures in aggregate samples using X-ray tomography tests.
