Any opinions on use of fibers in PCC pavements?
(OP)
I am told by a local sales rep that using fibers (specifically “Forta Ferro”) in roadway pavements can increase fatigue capacity of the roadway section, decrease thickness of base coarses, decrease concrete thickness, enhanced crack control etc.
Does anyone out there have experience with this? I am particularly interested in saving money by doubling the distance between transverse joints (currently located at approximately every 15 feet). If this is realistic, I figure I can save a bunch of money on the labor and material (joint fillers, sealants, dowels, etc.) by increasing the spacing of the joints. This would also translate into a reduction in long-term maintenance costs.
Any comments would be greatly appreciated.

I doubt if the local authorities will allow for a drastic change in such elements as base thickness and joints but fibers do improve the stress resistance and improve crack control.

Fibers will help to keep any random cracks tighter, but will not prevent them. In addition to ACI checkout ACPA at www.pavement.com
