Infrasense Utilizes Innovative 3D GPR Technology
Infrasense is at the forefront of pavement evaluation, using cutting-edge 3D Ground Penetrating Radar (3DGPR) technology to enhance the analysis of asphalt concrete (AC) pavement. Recently, the company undertook an extensive project on a significant interstate, allowing for valuable insights into the pavement’s underlying structure.
Detecting Issues Beneath the Surface
The primary goal of the evaluation was to pinpoint drainage issues suspected within the base layer beneath the AC pavement. By using a 3DGPR sensor operating at frequencies between 200 and 3,000 MHz, Infrasense was able to capture detailed data that identifies various subsurface features.
Depth and Activity Analysis Methods
Through a combination of depth analysis and activity data analysis, the company determined key characteristics of the pavement structure. The depth analysis accurately measured how deep the base layer lies across the evaluated section, while the activity analysis focused on identifying areas of high reflection activity (HRA) indicative of potential moisture accumulation in the base layer.
Advanced Data Presentation Techniques
Infrasense presented the findings in a comprehensive format, detailing regions of high reflection activity along with their geographical coordinates. This enables easy overlaying on maps or satellite images using geospatial software, providing a clear view of where interventions might be necessary.
Impact of High Reflection Activity
High reflection activity can be a critical indicator of moisture within the pavement's base layer, which, if left unaddressed, could lead to structural failures over time. By identifying these areas promptly, Infrasense empowers transportation agencies to make informed decisions regarding maintenance and repairs.
