Relating Compaction Performance & Behavior to Process Conditions

Executive Summary

During this reporting year, we focused on the following activities:

• Parametric studies were conducted that elucidate the effect of the differences in material properties of two components in a mixture on the strength of the mixture and some reasons that there is a deviation from the rule of mixtures.

• Appropriate definitions of damage were derived in order to understand the evolution of the strength of a compacted mixture during the compaction/unloading/ejection sequence.
• The issue of damage directionality become obvious in a parallel leveraged project. We present here only a single yet important relevant simulation. Detailed presentation of this topic will be done in the final report.
