Accelerated bridge construction, also known as ABC, has gotten more popular in recent years because it reduces the amount of time that a road or bridge must be closed during construction. DOTs don’t want to inconvenience their taxpayers due to road closures and traffic disruptions, especially in high volume urban areas. ABC offers a solution by reopening roads and bridges much faster than traditional bridge construction.
UHPC plays an important role in ABC projects. Bridge decks can be mostly prefabricated off site, then joined with UHPC in a joint fill or overlay on site. UHPC’s accelerated strength gain means the deck will achieve drivable strengths in as little as 3 days, so the road or bridge can be reopened quickly.
Another reason DOTs are utilizing UHPC is for its excellent performance under extreme conditions, such as exposure to harsh salts in coastal areas. SMARTUP UHPC can help protect other bridge elements by resisting corrosion much better than traditional concrete, extending the life of any road or bridge project.
