Intelligent Compaction (IC) Initiative An Overview and Accomplishments

Intelligent Compaction (IC) Initiative An Overview and Accomplishments Michael M. Arasteh USDOT, FHWA, TST EDC Exchange for Local and Tribal Agencies April 3, 2014 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. Single Drum IC Rollers Ammann-Case Caterpillar HAMM-Wirtgen Soils and Subbase Bomag Dynapac Sakai Double Drum IC Rollers

HAMM-Wirtgen Bomag Caterpillar Pending Asphalt Sakai 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 Pooled Fund (ICPF) ND MN NY WI PA MD IN VA KS

3 National Leader PR IC Benefits Research 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 Improve density.Better density.Better performance performance Improve Improve efficiency.Cost efficiency.Cost savings savings

Increase Increase information.Better information.Better QC QC Overall Overall Benefit: Benefit: Improved Improved Pavement Pavement Performance! 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, and 18 states developed specifications for IC.
