Livingston County, Illinois
Summer 2009

Challenges
The 8.5 miles of roadway was 20 feet wide and had an aggregate base. It had no safety shoulder and was rutted and rough. The average traffic count was 400 vehicles per day. The project had a limited budget.

Solution
Recycle with full-depth reclamation using engineered emulsion, Fortress,™ 8 inches deep.

Construction Phasing

Phase 1: Widen roadway to 24 feet (completed in 2008).

Phase 2: Pulverize existing surface and blend with widening aggregate.

Phase 3: Stabilize 8 inches deep with Fortress.

Phase 4: Trim final surface with full-lane rotomill after curing.

Phase 5: Apply A-2 bituminous surface treatment.

Phase 6: Apply center line stripping

Results
• Project completed within budget.
• New pavement consists of 8-inch stabilized base course.
• Project completed in stages with 4 miles done in 2009.
• Proposed 4.5 miles to be done in 2011.
