Falling Weight Deflectometer and Life Cycle Cost Analysis of a Major Urban Arterial Roadway Rehabilitated Using a Foamed Asphalt Stabilized Base
Bibliographic record
Abstract
Marine Way in Burnaby, British Columbia is a major commuting route in Greater Vancouver. The roadway is currently subjected to Annual Average Daily Traffic (AADT) over 20,000 vehicles. As such, there was emphasis for construction activities to minimize delays to the travelling public. The Falling Weight Deflectometer (FWD) was used extensively in the design, construction, and post-construction phases of the project. A Life Cycle Cost Analysis (LCCA) suggested that the use of reclamation and base stabilization would provide significant savings from the alternate options. The rehabilitation strategy considered not only the long term road rehabilitation solutions but also environmental impacts and delays to the traveling public. The road was reconstructed in 2011 utilizing full depth reclamation with a Foamed asphalt Stabilized Base (FSB). During the construction phase of this project, the FWD was used to test the various stages of the foamed asphalt process, particularly at the top of the FSB surface, and at the completed asphalt surface. This data was used to verify the AASHTO design layer coefficient of the FSB layer. This case study documents the rehabilitation option selection process, construction impact mitigation measures and provides the economic justification for proceeding with the selected rehabilitation method.

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.
