Field study on intelligent compaction for compaction quality control of subgrade bases
Bibliographic record
Abstract
To address the challenges in adopting intelligent compaction as the primary method for compaction quality control, this study investigated methods for determining appropriate target intelligent compaction measurement values (ICMVs) for compaction quality control and strategies to manage compaction quality considering the ICMV variability. Field tests revealed that the mean compaction meter value (CMV) increased with the number of roller passes. However, a high coefficient of variation was observed across all roller passes, indicating significant local variability in compaction quality. A 5 m region of interest was determined optimal for correlating CMV with plate-load-test results and determining CMV for compaction quality management. Uniform compaction could not address localized variability in compaction quality. Detecting weak areas during the compaction process and concentrating efforts in these regions improved the uniformity of the compaction quality. This study provides valuable insights for ICMV-based compaction quality control, assisting construction supervisors in setting target ICMVs, and developing effective strategies.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
