DRIVING IN THE FAST TRACK

Iowa is using quick setting, fast track concrete which allows traffic back on the pavement within 24 hours. Fast track is a combination of quick setting mixes and coordinated construction teams. The pavements are constructed to last 30 years. Details of the installation are described. The quick setting concrete was mixed with conventional equipment. With refinement, new equipment may be developed that mixes concrete immediately in front of the paver, a process that would allow even quicker setting concretes. To maximize curing, a heavy coat of curing compound was applied and an insulating blanket was used to cover the concrete. Although fast track construction adds $1 to 2/sq yd to the costs, the increase is offset by reductions in traffic rerouting and liability.
