ACPA Concrete Pavement Progress - Winter 2022-23

CONCRETE PAVEMENT PROGRESS 12 WWW.ACPA.ORG DIVIDED HIGHWAYS (URBAN) I-49 Reconstruction Jasper County, Missouri CONTRACTOR: Emery Sapp & Sons Inc.* OWNER: Missouri Department of Transportation ENGINEER: Missouri Department of Transportation The I-49 reconstruction in Jasper County, Missouri, had been needed for many years due to joint deterioration in the existing concrete pavement. The Missouri Department of Transportation designed a project where the existing concrete shoulders would remain in place. This was done to get the best value out of the cost of the project. The existing mainline was removed and replaced while minimally touching the existing subgrade. Rubbilization was achieved with guillotine breakers after the mainline was sawed from the shoulders. Paving began before all the breaking and removals were completed. In addition to the mainline concrete replacement, there were acceleration/ deceleration lanes and two loop ramps that were removed and replaced. Because MoDOT agreed to a full closure of the interstate in one direction, there was an incentive/disincentive clause in the contract to minimize the length of the full closure—$35,000 per day up to a maximum incentive of $350,000. Emery Sapp was able to work efficiently and effectively, opening the southbound lanes in just six days. A week later, the northbound lanes were closed and the work was completed in 11 days. Emery Sapp paved around the clock until the work was complete, placing 46,858 square yards. Emery Sapp achieved the entire incentive amount on the 87-calendarday project. GOLD
