A structure that symbolizes US bridge engineering of the 1930s, the Pulaski Skyway, which links Newark to Jersey City has been partially closed as it undergoes a considerable rehabilitation - the largest in its history. The project was a perfect opportunity for the Federal Highway Administration (FHWA) and the New Jersey Department of Transportation (NJDOT) to take full advantage of the technical benefits offered by Ductal® Infrastructure joint fill over the 5.5km long bridge from Newark Airport to the Holland Tunnel.
The Chillon Viaducts have been reinforced by an Overlay of Ductal® UHPC. Thanks to its mechanical characteristics and its durability properties, Ductal® was the only material able to provide an efficient retrofitting preserving the bearing capacity of the bridge, a lower maintenance cost and a quick retro commissioning of an important axis of the Swiss highway network. The two Chillon Viaducts are among the most spectacular infrastructure works of the Swiss highway network. Ductal® was prescribed for the reinforcement of the two decks (2.2 km long by 12 m wide each). The implementation of thin layer of Ductal® (4 cm thick) with rebars, allowed the strengthening of the bridge decks for shear loads, bending, and fatigue while ensuring the waterproofing of the surface.
The Honghe Suspension Bridge between Honghe Hani and Yi Autonomous Prefecture in Yunnan Province, South of China was completed within 35 days.
Mauves sur Loire bridge
The rehabilitation of Mauves-sur-Loire bridge consists in substituting the existing deck (3,500 m²) made of brick vaults with a thin deck made of thin precast UHPFRC slabs. The main objective of the project is to upgrade this historic landmark by increasing its bearing capacity and allowing the addition of cantilevered footbridges.
