Pavement Scanner

The ESS 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, such as too little binder, different aggregate, etc.

Maps of compaction and temperature provide a measure of uniformity that cannot be obtained from spot measurements from traditional density gauges. These maps in turn enable better Q/A and Q/C, and ultimately reduced costs.

Costs and risks associated nuclear sources are eliminated. No more nuclear safety training classes. No more source licensing headaches.
