I-57 | Sikeston, Missouri

Precast prestressed pavement was used to replace a 45-year-old jointed reinforced concrete pavement that had reached serviceability failure on I-57 near Sikeston, Missouri. The panels spanned the full 38 foot width of the roadway, including both traffic lanes and inside and outside shoulders. A rooftop pavement crown was cast into the surface of the panels by varying the thickness of the panels. The panels were installed over a permeable asphalt-treated base. Plain dowelled expansion joints were utilized for the joint panels and stressing was completed from blockouts in the joint panels rather than at central stressing panels.
