A comprehensive system for AASHTO PP67-10 based asphalt surfaced pavement cracking evaluation
Bibliographic record
Abstract
In light of the newly released AASHTO cracking protocol PP67-10 and high quality cracking data produced from a novel 3D 1 mm pavement data collection and automated analysis system, this paper develops an index system for overall cracking evaluation. The Analytical Hierarchy Process (AHP) is employed to establish a general framework and fuzzy set theory is adopted to convert actual severity and intensity measures into normalized scores. Multiple data combination techniques are applied for data aggregation. The ultimate product of this system, a single number cracking index representing the overall cracking condition, can be used to rank pavements and prioritize crack-oriented maintenance and rehabilitation projects. Furthermore, cracking indices for different pavement zones can also be derived from the system, which would be significant to examine the pavement failure mechanism. A case study containing 10 pavement sections is performed to demonstrate the applicability of this proposed evaluation system.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
