Consolidation

« Back to Glossary Index

The process of making the freshly placed PCC into a more uniform and compact mass by eliminating undesirable air voids (entrapped air) and causing it to move around potential obstructions (such as reinforcing steel). Sometimes this process is referred to as “compaction” however this Guide attempts to make a distinction between <em>consolidating</em> PCC and <em>compacting</em> HMA – two very different processes.
