Abstract
Large bridges require expansion joints to accommodate thermal expansion and contraction as well as movements induced by seismic events. Virtually all expansion joints create additional noise over and above that due to normal tire-pavement interaction. Researchers in Japan investigated modular expansion joint noise and created a full-size replica of a modular expansion joint in a test compound. They postulated that the croaking noise was created when pulses of air are injected into the joint cavities by tires rolling over the gaps between lamella beams. To provide a long-term solution to the joint noise issue, the joint cavities were first filled with geotextile material and then 'capped' with strips of 6 mm thick solid neoprene rubber, The caps, which were bonded to the flanges of the lamella beams keep the geotextile material in place and exclude water and debris from the joint.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
