Iowa DOT's New Modulus Verification Using Roller Mapping of Pavement Foundation Layers Special Provision Being Piloted on Highway Projects

Iowa DOT’s new MODULUS VERIFICATION USING ROLLER MAPPING OF PAVEMENT FOUNDATION LAYERS Special Provision is now being piloted on highway projects.

 

What this means for contractors:

✅ Use your rollers outfitted with e-compaction technology.
✅ Get real-time color maps of subgrade, treated soils, and granular base.
✅ Verify compaction and modulus targets before paving begins.

This is about more than digital verification; it’s about saving time, reducing rework, and building longer-lasting pavements.

Proud to see Ingios technology helping Iowa DOT and contractors lead the way toward performance-based construction.
