Intelligent Compaction
• What is IC?• IC History in FHWA,• EDC National Performance Goals,• IC Benefits, and• Accomplishments.
What is Intelligent Compaction?• IC Roller - FHWA Requirements:
IC Measurement Value (ICMV),
High Precision Positioning Systems (HPPS),
On-Board, color-coded display,
Surface temperature measurement system (Asphalt rollers only), and
Raw data that is Veda-compatible.

IC History in FHWA• TPF-5 (128) - A study on actual pavement projects,• ICPF was a 3-Yr research,• 12 states, and 16 Projects,• It completed in 2011, final report is available.• Research on following types of materials:
Soils,Sub base (including aggregate base), and Asphalt materials.

IC BenefitsResearch shows that IC allows for improved
roller passes.
More consistent passes that matched the optimum pass count established in the control strip were applied.
More consistent roller coverage will result in reduced variability in density.
Overall Benefits of IC
Improve density………….Better performance
Improve efficiency……….Cost savings
Increase information…….Better QC
Overall Benefit:
Improved Pavement Performance!
Accomplishments
34 states are implementing IC,3 lead states (CA, TX, and MN),29 projects completed in 2013,44 projects are to be constructed in 2014,10 demo projects are complete,6 pilot projects have been completed, and18 states developed specifications for IC.
