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.

EDC National Performance Goals
• Initiate construction of seventy five (75)
construction projects with IC being utilized
• Initiate construction of two (2) IC projects
by at least twenty five (25) distinct
transportation facility owners

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!
