A New Polymer Overlay for a Scranton, Pennsylvania, Bridge Deck



A GOMACO C-450 is followed by a Spanit® work bridge on a polymer concrete overlay project in Scranton, Pennsylvania.

Kriger Construction Inc., based out of Dickson City, Pennsylvania, recently completed a bridge overlay project in Scranton with their GOMACO C-450 finisher. The Pennsylvania Department of Transportation (PennDOT) required a one inch (25 mm) thick polymer concrete overlay on the existing bridge deck. The bridge, with four traffic lanes, was refinished two lanes at a time, which allowed traffic to run on the other two lanes. The GOMACO C-450 was set up at 32 feet (9.75 m) wide, with a finishing width of 24 feet (7.3 m).

The concrete was mixed on-site. The special polymer concrete mixing truck could be driven onto the deck, and placed the concrete in front of the finisher. A GOMACO Spanit® work bridge followed the C-450 giving the workers a platform for finishing work.






Kriger Construction specializes in bridge projects across the state of Pennsylvania.



The C-450 with double drums provided a smooth finish to the polymer mix design.
