The Florida Department of Transportation is currently using a method of replacing damaged concrete slabs on the urban Interstate System that results in minimum disruption to traffic flow and maximum safety for maintenance crews. The operation involves using accurate field measurements of damaged slabs to construct forms and pour new slabs in the maintenance yard rather than at the job-site. These cured slabs are then hauled to the area being repaired and placed on prepared subgrade. Removal of the old slab and setting of the new one are done at night beacuse of the lower traffic volume. As many as four slabs have been replaced during an 8-hour worknight. Slabs are set approximately 1/2 in. (12 mm) low and are raised to final grade by slab jacking. Joints are then sealed, and the road is ready for traffic. Careful planning and coordination of all crews involved in preparation and installation of slabs are necessary to ensure effectiveness in terms of smooth traffic flow and safety to workmen.
