Concrete Pavement Progress www.acpa.org 10 G R A N D S T R A N D A I R P O R T , S C Because the airport stayed open, there were a few safety con- cerns that had to be addressed, says Derek Johnson, project engineer for Hi-Way Paving. “We were able to set up a large concrete batch plant on airport property after obtaining the required permits. “We also had a gate close to the batch plant that we controlled, so all of our traffic came in and out that gate,” he says. “Because the airfield remained operational, we also had to be vigilant in preventing construction debris from getting into areas that planes were active.” Although there was no need to badge employees, the company was responsible for maintaining airport safety by monitoring people and activities onsite. Minor milling of the asphalt was needed to prepare the base for the overlay and there was some work to produce a uni- form cross-slope of 1.5%, especially at the points where the runway met taxiways and crossing lanes, says Wessel. The paving was performed by a four-track, stringless slipform paver and was completed in eight days, he adds. Feedback from Grand Strand clients has been positive, says Dunne. “They comment on the smoothness of the runway, but they also like the brightness of the new, white concrete,” he says. “Pilots can see it from a long way.” * ACPA member » continued from page 8
