Abstract:

The North Dakota Department of Transportation (NDDOT) plans to continue trialing the dielectric profiling system (DPS) after seeing how much information the technology can produce for assessing quality of paving mixtures and operations. DPS units use a ground-penetrating radar to assess the density of asphalt mixtures, a key indicator for pavement performance. The agency plans further practice with the unit and data analysis before incorporating it into its pavement assessment program. The agency’s current acceptance method is to obtain one set of cores for every 2,000-foot sublot. “I’m optimistic that after enough research, it can be used at least as a supplement to the traditional cores,” says Jonathan Stork, NDDOT Materials & Research.
