Engineer's Weekly Update


by Dave Van Duesen

Monday, July 17
Cells X39: CSM placed 3 and 4 inch fiber-reinforced concrete pavement in these sections.
Cells X27/X28: Pavement removal and excavation outside of bituminous lanes.
Cells X05: MnROAD personnel prepping for installation of bond breaker fabric.
Cells X38: Determined concrete pavement thickness using the MIT-SCAN-T2 device.

Tuesday, July 18
Cells 185/186 and 188/189: CSM installing subsurface drain. MnROAD personnel installing vaults, handholes and conduits.

Wednesday, July 19
Cells X39: Determined concrete pavement thickness using the MIT-SCAN-T2 device.
Cells 185/186: CSM installing subsurface drain. MnROAD personnel installing vaults, conduits, and sensors with University of Texas at El Paso (UTEP) researchers. CAT IC roller for UTEP project delivered to site.
Cells X39/X38: MnROAD personnel prepping joint opening sensor installations and conducting warp/curl data using ALPS2.

Thursday, July 20
Cells 185/186 and 188/189: MnROAD personnel and UTEP researchers installed sensors in subgrade. Mapping runs with the CAT IC roller made in the afternoon on 185/186. CSM installing subsurface drains adjacent to 187 and 188. UTEP will be conducting point tests (LWD, DCP) on the subgrade in 185/186.

Friday, July 21
Cells 185/186 and 188/189: FWD testing planned for 185/186 and 188/189. Mapping runs with the CAT IC roller proposed for the afternoon on 188/189. CSM will continue to install subsurface drains adjacent to 187 and 188. UTEP will be conducting point tests (LWD, DCP) on the subgrade in 188/189.

Look-ahead high points

  • See the attached look-ahead schedule for the weeks of July 24 and 31 provided by CSM today at the weekly meeting.
  • Concrete paving of Cells X05 now planned for week August 7.
  • Cells X05: Final cleaning/installation of fabric, and paving scheduled for next week Monday and Thursday, respectively.
  • Milling operations: CSM plans to perform all milling Tuesday and Wednesday, the week of July 24. This includes micro-milling on Cells 1 and 15, milling pavement for removal on Cells 127/227 and 128/228, and shoulders adjacent to Cells 2-4.
  • Excavation work in Cells 127/227 and 128/228 planned for late the week of July 24 into early the week of July 31.
  • Surfacing construction of the NRRA PM sections (micro-surface and thinlays in Cells X01/X15) is planned Friday, July 28.
  • Construction of the NRRA CCPR sections is currently planned for middle to late August.
  • Disregard the last activity “Common Excavation” in Cells 133-233 and 135-235. This is an error and is not planned.
  • Traffic is planned to be switched early in September to facilitate construction of the HMA overlays on the original WB I-94 concrete.
