• Abstract:
  Optimistic about dielectric profiling systems' (DPS') effectiveness in improving pavement performance and assessing compaction for acceptance, the Minnesota Department of Transportation is leading efforts to develop and fine-tune the technology. DPS use a ground-penetrating radar (GPR) to assess the density of hot-mix asphalt, a key indicator for pavement performance. MnDOT is the lead agency for a national transportation pooled fund study (Pooled Fund TPF-5 443) to address research gaps and share resources with other State highway departments on making DPS more viable as a method to evaluate quality in pavement construction. "Because one thing we can all rally around is that nobody likes cutting cores in our pavements," says Kyle Hoegh, MnDOT Office of Materials and Road Research. "...There’s an incentive for all parties involved to work towards something better."
