6. 3D Laser System 3D Camera Linescan Lasers Macrotexture Laser
Digital image of roadway
3D Linescan Camera gives us a 3D image of roadway (measures rutting)

7. 2D Digital Image of Roadway
Digital Image of Roadway: (Used to conduct surface ratings at workstation)
3D Image of Roadway: (lighter=roadway close to you, darker=further away) Gives you visual of rutting
Surface rating identifies distresses on pavement surface
3D Image allows user to identify rutting in pavement section as well as cracking distresses

11. MnDOT Experience 15+ years’ experience with Pathway equipment
1997: First Pathway van, using VCR’s to record images.
2005: Two new vans purchased and began surveying counties. Started using digital cameras and scanning lasers in back of van for rutting.
2011: Two new vans with 3D technology.
