Abstract:

In 1997 ODOT overlaid the Link River Bridge with microsilica concrete, reinforced with polypropylene fibers (FMC). The manufacturer claimed the fibers would reduce plastic shrinkage cracks and settlement cracking during the early life of the concrete, as well as reduce the formation of intrinsic cracking. The northbound lane was constructed with the FMC while the southbound lanes were constructed with plain microsilica concrete. Neither side showed much initial cracking when the curing blankets were removed. The latest inspection two years after construction found only minor cracking in the northbound lane and very little in the southbound lanes. 25 p.
