FLUID MOVEMENT : DOTS USING LIQUID RESIN FOR SLAB REPLACEMENT STABILIZATION

The Colorado Department of Transportation, working with Uretek USA, devised a new way to restore concrete pavement using liquid resin to level and anchor precast slabs. This lead to the successful completion of the world's first full-panel slab replacement. The panels were manufactured to within 1/8 in. tolerance of field measurements, well within the 1/2 to 3/4 in. tolerance permitted under the contract. The liquid resin was pumped in through injection holes the size of nickels to stabilize, fill voids and provide a large lift area. The polyurethane reaches 90% strength in just 15 minutes. Fiberglass load transfer panels were "stitched" between the old slabs and the new ones and the joints filled with sealer. CDOT used the technique on heavily traveled I-25 to carry out repairs at night. The California Department of Transportation has also started using the technique.
