FHWA Intelligent Compaction National Workshop - No.3

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 color-coded 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.
