What is Intelligent Compaction (IC) and how can it make paving operations more efficient, accurate and profitable?

According to the Department of Transportation (DOT) Intelligent Compaction refers to the compaction of road materials, such as soils, aggregate bases and asphalt paving materials, using vibratory rollers equipped with an integrated measurement system, Global Positioning System (GPS), on board computer reporting system, and for asphalt non-contact thermal sensors.

The use of IC rollers allow for real-time monitoring and just-in-time corrections in the compaction process. IC rollers also maintain a continuous record of roller passes, IC measurement values relating to stiffness, vibration frequency/amplitude, and roller speeds. This technology can help meet asphalt compaction and soil compaction specifications for federal and state highway contracts.

Benefits of Intelligent Compaction:

  • Improved rolling efficiency
  • Better quality control and uniform asphalt and soil consistency
  • Increased productivity
  • Fewer passes, fuel savings, operation savings
  • Continuous record of material stiffness values
  • Reach target compaction and documentation of data (results)

As implementation of Compaction Control technology becomes standard for paving jobsites, the use of Intelligent Compaction equipment is more than a smart choice. It is becoming a requirement by state highway agencies nationwide.
