SA Technical memorandum No. 11-SA-01 has guidelines on how to design flexible pavement
For 10-ton Flexible Pavement design, designers must use either:
MnDOT R-Value chart or MnDOT Flexible Pavement Software or
MnPave Software State Aid – Ultimate 10 Ton Staged
Use the “Ultimate 10 Ton Staged Flexible Pavement Design” chart.

Currently, designers use MnDOT Rigid Pavement Design software.

Installation History of ATR’s - MnDOT 1960’s – ATR’s (loop detectors) 14 ATR’s were installed on CSAH and MSAS 1995 – Upgraded to new models capable of doing
VC
At the moment: 3 ATR’s installed couple of years ago 5 installed this year(2011/2012) – 4 waiting for
power and phone connection 14 to be upgraded, 1 new for 2012/2013 Total # of ATR’s on State Aid routes will be 23
The whole idea of these ATR’s is to improve traffic data collection on local roads, including VC.
Future plans 2 new WIM’s or Upgrade existing 4 ATR’s to WIM’s Portable WIM’s
