Work was performed in temperatures from 18° to 49° degrees Fahrenheit. Rapid Set® DOT Cement’s high early strengths allowed the concrete to be exposed to freezing temperatures that portland cement concrete typically can’t handle.
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.
Time is of the essence when you’re rehabilitating infrastructure used by 40 million vehicles a year. The Port Authority of New York & New Jersey chose two Rapid Set® products because they eliminated the need for admixtures as well as met a tight opening strength requirement.
Maintenance crews from the Missouri DOT’s Northeast District sprang into action when drivers reported a large hole in a bridge deck one winter morning. By using Rapid Set® DOT Cement to repair the damage, the state was able to reopen the bridge to traffic 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.
