A study was done on a model bridge with precast deck panels to see how well they work. The goal was to test the panels' strength and durability. The researchers used a small-scale model of a real bridge and tested the precast panels to see how they held up under different conditions. They found that the panels were strong and could handle a lot of weight without breaking. This means that using precast deck panels in real bridges could be a good idea for making them stronger and safer.
