DMap – A New Way to Map Density and Air Void Content in Asphalt Using AIR GPR

For Pavement Quality Control

Proven Results with Minnesota Department of Transportation (MnDOT)

Trunk Highway 22

Orbit DMap assessed 63.26 miles, an average density of 93.4% with reduced variability and fewer core samples needed.

Trunk Highway 15

Over 28.4 miles, DMap showed a 93.9% average density, saving costs by minimizing disincentives and improving quality.

Trunk Highway 35

DMap reporting showed enhanced density consistency in a 34.83 mile stretch with much faster collection and allowing reduced coring compared to traditional methods.

QC/QA for New Pavement Construction:

Minimize Risk, Maximize Longevity

Achieving optimal pavement density and air void content is critical to ensuring the structural integrity and long-term performance of new pavement. Accurate compaction directly reduces future maintenance costs by reducing the likelihood of long-term failures such as cracking, rutting, and premature wear – ultimately protecting your investment.

Instant Results, No Technical Bottlenecks

With Kontur DMap, you get automated, push-button dielectric evaluation of pavement density across the entire road area – delivering actionable insights within minutes.

The Kontur DMap data is separate from traditional GPR data, and eliminates the need for complex manual analysis, accelerating your quality assurance process without sacrificing accuracy.

Clear Data for Confident Decisions

Kontur DMap provides intuitive, easy-to-read visualizations that empower field teams and decision-makers alike, making it simple to use, even without specialized GPR expertise.

This means faster QA cycles, streamlined workflows, and better-informed decisions – keeping projects on time and on budget.
