What happened: During recent pavement assessments, the Minnesota Department of Transportation (MnDOT) showcased Kontur’s Orbit DMap, a cutting-edge density profiler that scans asphalt pavements to deliver real-time dielectric responses correlating to pavement density. Tested on Trunk Highways 22, 15, and 35, DMap provided full-coverage density maps, reporting average densities of up to 93.9 percent with reduced need for destructive core sampling.
Why it matters: Poor pavement compaction leads to premature failures like cracking and rutting, costing millions in repairs. DMap’s non-destructive, automated analysis and reporting immediately highlights the areas of concern. The Kontur DMap system is collected from the safety of a vehicle and offers a wide collection footprint, allowing full lane width evaluation. MnDOT’s data shows DMap improved density consistency and saved costs by minimizing contractor disincentives.
