The Ultra-JS™ system is a patented prefabricated deck joint system designed to improve the connection between adjacent bridge spans. The system uses a precompressed ultra high performance concrete (UHPC) joint element that is manufactured offsite and then installed between girder-supported deck segments. Unlike traditional cast-in-place joints, Ultra-JS™ enables rapid, controlled field installation while maintaining the necessary compressive forces across the joint. This design enhances long-term durability, reduces cracking, and accommodates deck movement without the need for conventional expansion joints. By combining the benefits of precasting, UHPC durability, and precompression, Ultra-JS™ offers a high-performance solution for jointed bridge decks in accelerated construction environments.
