Prefabricated pavement sections were laid over a grout base when it became necessary to replace an entire section of the eastbound traffic lane on state route 101 in California. A thickness of 0.67 ft. was selected for the prefabricated concrete slab and it was formed and poured in an open area approximately 1500 ft. from the repair zone. Forms utilizing 2-inch by 6-inch timbers faced with 3/4-inch plywood were constructed and dimensioned to provide a clear space of approximately 0.1 ft. on all sides of the slab. Lifting inserts were placed at points approximately 1/6 span in from the slab edges. Details are described of the concrete mix and various aspects of the repair work. The total elapsed time for the operation, including traffic control measures, was 7 hours and 15 minutes. The true work time was 5 hours and 30 minutes. The total cost for the operation was under $3,000.
