The NUDECK precast concrete deck system was improved to make bridge construction faster and easier. The new system uses full-width full-depth deck panels to reduce the number of joints and speed up construction. It also includes special features like self-consolidating concrete and post-tensioning to enhance durability. The researchers tested these features in full-scale experiments and found that the system works well. The self-consolidating concrete can be pumped easily and the post-tensioning components perform as expected. Overall, the second generation NUDECK system is a success in simplifying bridge construction and improving durability.
