Work was performed in temperatures of 18° to 49° degrees Fahrenheit. The high early strengths of DOT Cement allowed the concrete to be exposed to freezing temperatures unlike portland cement concrete.
The fast-setting cement is on SCDOT’s list of qualified products because it meets all specifications. It includes air-entrainment where freeze-thaw cycles are prominent and a superplasticizer for better workability.
The Helix Fix project included performing concrete structural work, repaving the road, and installing new median barriers. DOT Cement and Low-P Cement were used.
MoDOT's Northeast District bridge crews immediately closed the westbound lane of the 67-year-old bridge to repair a large hole. By using DOT Cement for this emergency repair, traffic was reopened to travelers the same day.
The George Washington Bridge carries more than 106 million vehicles a year, making it the world’s busiest motor-vehicle bridge. The pothole-riddled north- and south-bound access ramps that connect the bridge to New York State Route 9A needed to be repaired. The Port Authority needed to reopen the busy ramps in a timely manner to not disrupt traffic patterns. Products used include Concrete Mix and DOT Cement.
