Phase Two Ideas

National Road Research Alliance Logo

We have decided on the following research ideas for the future of the alliance and MnROAD.

Preventive Maintenance

  • Spray on Rejuvenator Synthesis
  • Spray on Rejuvenator Test Sections
  • Service Life Enhancement of Substrates Overlaid with Thin Overlays (UTWBC, Chip Seals & Microsurfacing) for each state
  • Concrete Pavement Restoration (CPR) for Bonded Concrete Overlays of Asphalt (BCOA)

Flexible

  • Mix Rejuvenator Synthesis (Phase-1)
  • Mix Rejuvenator Test Sections (Phase-II)

Intelligent Construction Technologies

  • Evaluation of Levels 3-4 Intelligent Compaction Measurement Values (ICMV) for Soils Subgrade and Aggregate Subbase Compaction
  • Support Importing, Viewing and Analysis of Dielectric Constant Data in Veta
  • HD and VHD Seismic Approaches for Roadway Evaluation

Geotechnical

  • Mechanistic Load Restriction Decision Platform for Pavement Systems Prone to Moisture Variations
  • Environmental Impacts on the Performance of Pavement Foundation Layers
  • Permeability of Base Aggregate and Sand
  • Improve material inputs into mechanistic design properties for reclaimed HMA Roadways

Rigid

  • Construction Report for Jointless FRC Roundabout in Minnesota
  • Incorporate Joint Faulting Model Into BCOA-ME
  • Engineered Dowel and Tie Bars combined with LTPP SPS-2 Determination of Causes for Cracking Over Dowel Bars
