FHWA Intelligent Compaction
Salt Lake City, UT – 2/28/2012
Intelligent Compaction (IC) is an equipment-based technology for better quality control that results in longer pavement lives. IC machines are vibratory rollers with accelerometers mounted on the axel of drums, global positioning system, infra-red temperature sensors (for asphalt), and on-board computers that can display colorcoded maps in real-time to track roller passes, asphalt surface temperatures, and stiffness of compacted materials.
The FHWA has been leading a national effort to advance the IC technology through numerous projects since 2008 to improve compaction quality of materials that include granular soils, cohesive soils, stabilized base, and Hot Mix Asphalt (HMA) pavements. To further accelerate the implementation of IC, FHWA is conducting IC national workshops for technology transfer and training.
The purposes of this workshop are to:
• Familiarize attendees with fundamentals of intelligent compaction;
• Demonstrate the route to successful IC implementation; and
• Develop attendees into technology champions of IC for their organizations or companies.
