Abstract:Interstate 80, which traverses Iowa in an east-west direction, has been showing various signs of deterioration be-cause of heavier than anticipated truck traffic, both in volume and in truck weight. Several solutions have been tried, includ-ing complete replacement by a new inlay, full-depth patching, asphalt overlay, and portland cement concrete (PCC) overlay. Several factors favor PCC overlay, including economics, con-struction time, increased load capacity of the new pavement, and the need to minimize the consumption of new resources. The design provides for a 4-inch (10.2 cm) thick PCC overlay over the old lo-inch (25.4 cm) thick pavement. Preparation for the overlay required numerous full-depth patches of deteriorated joints, followed by shotblasting, milling where needed, and the application of a cement water grout. This paper discusses the design, contract requirements, construction procedures and pave-ment performance to date.
