Abstract:
The article provides details of rapid rehabilitation of a bridge approach slab on I-10 near Quincy, FL, using precast concrete panels. The existing cast-in-place approach slab had been in service since the bridge was constructed in 1976, and it was exhibiting cracking and settlement. The rehabilitation only required a total of 2.5 days to allow for continuous construction during the two travel lane panel placements, all the time maintaining one lane open for traffic.
