Abstract

Placing a concrete overlay directly on top of an older asphalt pavement is a procedure that has been used sporadically by transportation agencies for the past quarter century. This practice is now receiving more attention because of initial cost savings and because this type of concrete overlay has shown better than average long-term performance as a resurfacing strategy. Nebraska Department of Roads (NDOR) has three whitetopped sections that have been in service for between thirteen and twenty-three years. Based upon evaluation of pavement performance for existing whitetopped sections and a cost comparison of alternatives, NDOR recently authorized construction of a new whitetopped section on U.S. Highway 2. Performance of this new section is being closely monitored to obtain data on the long term cost effectiveness of whitetopping as a pavement rehabilitation strategy.
