Abstract

fetched live from OpenAlex

Permeable Interlocking Concrete Pavement (PICP) rapidly drains surface water through its paver joint spaces and therefore has the potential to prevent ice from forming during winter conditions. As a result, PICP may reduce the amount of road salt needed for de-icing paved surfaces, and it may also reduce the risk of pedestrian slipping and vehicle skidding. PICP also has the potential to reduce chloride concentrations released to the environment from winter salting practices, as melted ice and snow are temporarily retained within the aggregates of its base and subbase layers. This study evaluates the performance of an outdoor PICP and asphalt test pad over two winter seasons in Vaughan, Ontario by assessing differences in surface conditions, surface friction, surface temperatures, and chloride concentrations. PICP was found to prevent melted ice and snow from refreezing, have less drastic reductions in surface temperatures at sunset, and attenuate and delay chloride concentrations.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame distilled prediction

Teacher imitation

Not 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.
