Infrasense conducted a vehicle-based pavement thickness survey and report for a 13-mile segment of Interstate 85, that contains multiple lanes and ramps, in Jackson County, Georgia, USA. It was found to have a continuous concrete layer underneath the wearing asphalt surface.
Infrasense methods have addressed a variety of pavement structures including:
• Composite pavements
• Continuously reinforced concrete pavements (CRCP)
• Jointed plain concrete pavements (JPCP)
• Jointed reinforced concrete pavements (JRCP)
• Asphalt over granular base
“… including nondestructive testing of highways in California, Connecticut, Georgia, Idaho, Indiana, Massachusetts, Maryland, Minnesota, New York, Oklahoma, South Carolina, Tennessee, Virginia, and Vermont.”
This project provided the client with:
• Tabular and graphical datasets
• Plotting at 5-ft intervals along the wheel-paths of each lane
• Each point linked to precise GPS coordinates
• Help in visualizing how the constructed layers of the roadway change in thickness along the length of each lane
• Identifying areas of potential settlement and moisture intrusion
• Survey conducted at driving speed
• No closures
• No disruption to traffic
• Zero impact on the integrity of the road
The GPR data collection system was made up of a 1 GHz horn antenna and a SIR 30 control unit. The final report included a quantitative summary of average layer depths in each lane, along with visual plots showing the sub-surface strata along the length of the section.
The GPR pavement surveys are carried out according to ASTM D4748-10. The resulting data shows a cross-sectional slice of the pavement strata at various offsets. Each slice includes the surface and any material change in the first few feet below the surface. The data is processed and analyzed using proprietary internally developed software specifically designed for pavement and bridge assessments.
This past year, Infrasense evaluated the pavement profile and condition of over 2500 miles of pavement across 30 unique projects including nondestructive testing of highways in California, Connecticut, Georgia, Idaho, Indiana, Massachusetts, Maryland, Minnesota, New York, Oklahoma, South Carolina, Tennessee, Virginia, and Vermont.
