2011 MnROAD Mainline Concrete Construction: Cells 5, 6, and 63

In September 2011 MnDOT constructed two cells in the MnROAD Mainline in continuation of the study of unbonded overlay (Cell 5) and to facilitate studies on a drainable base (Cell 6) with a longitudinal tined texture. Additionally, roller-compacted concrete shoulders were constructed in these cells to replace the preexisting asphalt shoulders. Finally, repairs were done to a thin concrete overlay of existing asphalt pavement installed in 2004 (Cell 63). This report discusses the construction procedure, instrumentation and the initial monitoring from these test cells.
