PART 3 EXECUTION <br />3.01 GENERAL <br />A. Subgrade preparations shall be performed to produce the required density, grade, and <br />cross-section. <br />3.02 PREPARATION <br />A. Inspection of subgrade by test rolling conforming to MnDOT Spec. 2111, or as modified <br />herein: <br />1. The equipment used for test rolling shall be a Tandom Truck with a gross weight of <br />45,000 pounds. <br />2. The road bed will be considered unstable if yielding and rutting is greater than <br />1-1/2 inches. <br />3.03 COMPACTION <br />A. Conform to MnDOT Spec. 2105.3F1, or as modified herein: <br />1. For the Specified Density Method, the Engineer will sample and test the soils to <br />determine the Maximum Density and Optimum Moisture. <br />2. Density and moisture tests will be taken on the compacted subgrade at the location <br />and testing rates designated by the Engineer. Nuclear density testing shall be <br />considered an approved method. <br />3.04 FINISH OPERATIONS <br />A. Subgrade tolerance shall conform to MnDOT Spec. 2105.3G, or as modified below: <br />1. Not vary by more than 0.05 feet above or below the prescribed elevation at any <br />1 point where a measurement is made. <br />END OF SECTION <br />SUBGRADE PREPARATION <br />© 2015 Stantec 1 193803415 31 23 13 - 2 <br />
