Intelligent Compaction (IC) demo by the Minnesota Department of Transportation (MnDOT). IC is an improved method of compaction—IC rollers measure their effectiveness during construction and immediately display the results on screens inside the machines. In this video, watch HMA paving operations: view an introduction, the plant, and paving and roller preparations.
Construction teams are working towards uniform compaction—the road needs to be firm and even—and IC makes that goal easier to reach. An IC roller operator can monitor their compaction progress on a screen inside the IC roller.
Since uniform compaction leads to more durable roads, the ability to accurately monitor progress is important. IC rollers make this simple—their equipment collects data while compacting, and operators use the data to track their progress and adjust their procedure as necessary.
MnDOT's demo took place on CSAH 4 in Willmar, MN, from June 14 to June 23, 2008.
As well as improving the level of quality control, IC is intended to save time and reduce costs: IC can work as a replacement for conventional testing. Instead of stopping construction in order to test samples, workers can keep compacting while they gather data. Compaction data shows up on-screen inside IC rollers, reducing the need to go back and test cores from the road.
Since important data is immediately available inside IC rollers, construction teams can base their procedure on that feedback. This allows them to confidently and quickly achieve uniformly compacted roads.
