Event Details


The FHWA HMA density - Intelligent Compaction (IC) research team cordially invites you to attend an Open House that showcases asphalt IC technologies.

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 asphalt pavements.  To further accelerate the implementation of IC, FHWA is conducting IC demonstrations and open house events around the country.


The purposes of this open house are to:

  • Familiarize attendees with asphalt intelligent compaction technologies;
  • Demonstrate the route to successful IC implementation; and
  • Demonstrate IC equipment.

Target Audience

  • DOT Construction Engineers, QC/QA Personnel,  Spec Writers
  • Asphalt Paving Managers, Superintendent, QC Personnel
  • IC Roller Vendors and dealers
  • GPS Vendors


The Open House presenters include:

  • Victor (Lee) Gallivan, FHWA, COR of the FHWA HMA Density-IC research project
  • George Chang, Transtec Group, PI of the FHWA HMA Density-IC research project
  • Bob Horan, Asphalt Institute, facilitator of the FHWA HMA Density-IC research project
  • Tim Kowalski, HAMM/Wirtgen
  • Todd Mansell, Dave King, Caterpillar
  • Mike Mcmahon, SITECH-NW
  • Garry Aicken, Kessler
