Outline Data collection activities and schedule US 169/CSAH 8 Pavement preservation and MnROAD Cracking Group sections Overview of Pathways 3D data collection van and data analysis Preliminary ride data (before and after construction) NCAT data collection

Common Activities Joint Planning Meeting with Sponsors Performance Monitoring Dedicated Pathways Van Cracking Rutting Ride Texture Every 2 weeks beginning Spring/Summer 2017 Database Utilize the MnROAD common database with NCAT Common Analysis at NCAT

Data Collection Schedule Data to be Collected Frequency Analysis Cracking Bi Weekly (Van Survey) Video Manual Distress (monthly, office workstation) Manual Distress (field review – quarterly) AutoCrack (Bi Weekly, office workstation) Rutting Bi Weekly, office workstation Ride Texture FWD Quarterly Falling Weight Deflectometer GPR As Needed Ground Penetrating Radar WIM Continuously Weigh – in - Motion

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)

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 3D Image of Roadway 2D Digital Image of Roadway

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. Special thanks to Pavement Management office Dave Janisch, Shelly Pedersen, Elaine Miron, Mark Resemius, Gary Wallner, Tom Nordstrom

Data Collection Pre-construction collection: July 22 Post-construction collection : October 14 US 169 and CSAH 8 Post-construction run on Cracking Group Cells TBD After open to traffic, beginning of November Second run on Preservation sections in November, weather permitting
