In 1977, Washington County, Iowa, had to repair a 9-mile section of an old asphalt pavement. After studying all the options, it was decided to resurface the road with portland cement concrete. The only surface preparation for the asphalt surface was to clean it with a power broom. Nothing was done with the wheel ruts or chuck holes except to fill them with portland cement concrete as the road was repaved. This approach saved the expense of surface preparation and gave additional thickness of the concrete in the wheel ruts and edges where more strength was needed. The county used a computer program to assist it in designing the new portland cement concrete resurfacing with a 2-inch crown. After many years and 2,000 vehicles per day, no maintenance dollars have been spent on this road.
