Humboldt Pavement Scanner
Humboldt Pavement Scanner
The Humboldt Pavement Scanner provides both radar compaction and infrared temperature sensors and generates maps of asphalt compaction and temperature without the need for nuclear sources.
The Humboldt Pavement Scanner measures asphalt pavement density using advanced radar technology without using nuclear sources. The radar sensor continuously scans the surface to produce compaction or density maps. Additionally, an integrated temperature sensor generates pavement temperature maps. Temperature differences indicate locations where the asphalt mix is not uniform in terms of temperature or mix (i.e., too little binder, different aggregate, etc.). Cold zones and improperly compacted zones lead to premature failure of the mat.
The Pavement Scanner produces two-dimensional maps of the work area rather than a handful of measurements at specific locations. These maps of compaction and temperature provide much more information than the spot measurements of traditional density gauges. The scanner has an integrated GPS so that these compaction and temperature data can be exported into Google maps and sent to any smart device (cell phone or tablet) for viewing. The ability to view information in map for provides much better coverage, fast and easy interpretation, better Q/A and Q/C, and ultimately reduced costs.
A Better Alternative
The Pavement Scanner does not use any nuclear sources and does not emit dangerous radiation. Costs and risks associated nuclear sources are eliminated. No more nuclear safety training classes. No more source licensing headaches. The pavement scanner has been designed for high reliability and to be easy to use. All cabling has been eliminated to improve ease of use, and end common problems associated with connectors and cables.
What the Researchers are Saying
When laying down an asphalt mat, research has shown that cold spots are not compacted properly. The IR temperature sensor clearly delineates these zones. Compaction measurements from the radar sensor can be made even after the mat has cooled. The Transportation Research Board has published a detailed study that illustrates the the use of these instruments: Using Infrared and High-Speed Ground-Penetrating Radar for Uniformity Measurements on New HMA Layers, TRB, available at: http://nap.edu/22769.
