Abstract

fetched live from OpenAlex

In early 2011, a study was carried out to assess the condition of the haul road networks within three major active landfills in a large Canadian city. The purpose of this study was to identify and document the road segments within each landfill, determine the condition and structure of each road, and develop maintenance, rehabilitation or reconstruction (M, R & R) strategies based on the collected data. The pavement structures within each landfill consisted of flexible pavements (asphalt concrete), gravel pavements and dirt roads. The Route ID is an identifier used to develop a comprehensive pavement management database and to document all road segments within each landfill. The roads within each landfill were then sectioned using digital aerial images and site visits. Pavement attribute data was then collected for each unique identifier. To assess the condition of the pavements, condition surveys and deflection testing using a Falling Weight Deflectometer (FWD) were performed on all road segments. To identify the pavement structure, Ground Penetrating Radar (GPR) surveys and borings were advanced along each road segment. The collected data was then analyzed and used to develop M, R & R strategies for each roadway section. A prioritization methodology was also developed based on traffic levels, pavement thickness and structural condition. The pavement management methodology and prioritization strategy developed as a part of this study can be used by landfill operators to effectively manage their haul road networks and improve efficiency and operation. For the covering abstract of this conference see ITRD record number 201211RT334E.

Not 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.
