Technology Drive Street Improvement Project

Proposed Improvements

The City of Willmar is moving forward with planned improvements to the Technology Drive area. Design efforts are currently underway. The scope of improvements includes:

• Asphalt resurfacing
• Spot repairs to concrete curb and gutter
• Targeted storm sewer repairs

Construction Method

The project will utilize a Full Depth Reclamation (FDR) process. This involves grinding the existing asphalt pavement and aggregate base to create a recycled material known as “reclaim.” A portion of the subgrade will be excavated to accommodate a thicker aggregate base. The reclaimed material will be reused and capped with new aggregate base, which will be shaped, compacted, and paved with new bituminous surfacing.

The contractor’s general construction sequence is outlined in the construction newsletter. Additional clarification on the reclamation and street base construction sequence is provided below:

1. Full Depth Reclamation will be performed across all phases of Technology Drive.
2. Reclaim material from Phase 2 will be used as the new street base for Phase 3.
3. Reclaim from Phase 1 will be used for Phase 2, and reclaim from Phase 3 will be used for Phase 1.
4. All phases will then receive new aggregate base material, resulting in a strengthened street base.

Alternative Construction Access

Traffic Access During Construction

• During street base operations in Phases 2 and 3, access to Technology Drive will be maintained via the Phase 1 area.
• When construction shifts to Phase 1, access to the MinnWest Technology Campus will be provided via Phases 2 and 3 and through the Prairie Lakes Youth Programs access to Civic Center Drive.
