Abstract
This synthesis report will be of interest to pavement design, construction, maintenance, and materials engineers; geologists and hydrologists; highway contractors; and others interested in the maintenance of highway edgedrains. It describes the current state of the practice for the maintenance of highway edgedrain systems (i.e., outlet, headwall, connection, longitudinal/mainline pipe) and procedures to reduce and facilitate the maintenance of edgedrains. Information is provided on the maintenance of edgedrains, its relation to pavement drainage and performance, and the importance and cost benefits of providing good drainage in highways. Information for the synthesis was collected by surveying U.S. and Canadian transportation agencies and by conducting a literature search to document North American and European practices. This report of the Transportation Research Board is an extension to the information provided by NCHRP Synthesis of Highway Practice No. 239, Pavement Subsurface Drainage Systems (1997). Design, material, and construction details and techniques, obtained from a survey of North American transportation agencies, are provided to demonstrate effective edgedrain maintenance practices that promote highway drainage. Agency policies and procedures for edgedrain maintenance are also provided. In addition, strategies to reduce edgedrain maintenance costs and methods of increasing maintenance effectiveness are included.

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
