2017 Construction update week of Sept. 18

Engineer's Weekly Update


by Dave Van Duesen

The reason for the lull in updates is because there has been somewhat of a lull in action. Here’s a brief recap of major activities since the previous update:

Week of September 18, 2017:

  • WB I-94 traffic was transferred to the mainline test sections on Monday.
  • Final placement of asphalt surfacing on Cells 185/186/188/189, X27/X28, and X35 on Tuesday.
  • Uretek performed pre-overlay joint/slab stabilization of the concrete pavement of Cell 994 on the original westbound lanes of I-94. This particular section will be receiving an asphalt overlay along with 11 other sections for NRRA rehab and compaction studies.
  • MnROAD personnel began installation of environmental sensors (temperature and joint opening) prior to asphalt overlay construction.

 

Week of September 25, 2017:

  • Contractor performed pre-overlay milling of tapers on Tuesday.
  • Milling for partial depth repair sections throughout the week.
  • Starting Wednesday, MnDOT crews performed further preparation of the partial depth repairs and patching materials representatives were on hand to install their products.
  • Routine traffic loadings of the low-volume road resumed.

 

Week of October 2, 2017:

  • Continued work to install partial depth repair patching materials.

 

We hope that construction of the asphalt overlays on Cells 984-995 will begin sometime the week of October 9. Stay tuned for updates.
