Totaling 6 projects in 2020, Infrasense conducted non-destructive surveys and reports of over 500 lane-miles of pavement in the state of Georgia. The projects provided the client with continuous thickness data of asphalt and underlying base layers along each surveyed lane.

ATLANTA (PRWEB) January 25, 2021

Infrasense conducted pavement thickness surveys and reports for 6 unique projects in 2020 in the state of Georgia. These projects comprised over 500 lane-miles of pavement along travel lanes and ramps of major Interstate and State Highways. One project in particular included pavement structure data for each wheel-path of 12 mainline travel lanes and 64 unique ramp lanes. The projects all provided the client with tabular and graphical datasets plotted at a 5-ft interval along both wheel-paths of each surveyed lane, with each point linked to precise GPS coordinates. These datasets help visualize how the constructed layers of the roadway change in thickness along the length of each lane. The surveys were all conducted at driving speed with no closures, no disruption to traffic, and zero impact to the integrity of the roadways.

The GPR data collection system was made up of a 1 GHz horn antenna and a SIR 30 control unit, both manufactured by GSSI in Nashua, NH. The final reports included quantitative summaries of average layer depths in each lane, along with visual plots showing the sub-surface strata along the length of all sections.

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.

With a growing fleet of dedicated survey vehicles strategically in placed around the country, Infrasense is looking forward to an exciting and efficient year of work in 2021.
