This month, I’m back to my series of columns on factors affecting asphalt pavement performance. This column is about density and compaction. I believe density is the most critical construction property influencing pavement performance.

For asphalt pavements, compaction is the means of compressing the asphalt mix into a smaller volume. This process forces the aggregate particles together, which is necessary to increase the stability, rutting resistance and load-carrying capability...Full Story

A Federal Highway Administration (FHWA) Intelligent Compaction National Workshop is scheduled for February 28, 2012 in Salt Lake City, UT.

This event is free but there is limited registration. You can register online.

The workshop's aim is to familiarize attendees with the fundamentals of intelligent compaction (IC), demonstrate the route to successful IC implementation and develop attendees into champions for IC with their organizations and companies...Full Story
