Case Studies to Determine the Relationship between Rehabilitation Process, Hot-Mix Asphalt Lift Thickness, and Pavement Smoothness
Bibliographic record
Abstract
With the introduction of High Speed Inertial Profilograph (HSP), it has become possible to ascertain pavement smoothness accurately and instantaneously. HSP used for Highway smoothness testing in Ontario are ASTM Class 1 compliant, with capability to determining the smoothness of the pavement layer accurately and in a repeatable manner. The HSP can be operated at speeds of up to 80km/hr for prompt results with minimum interruption to traffic during smoothness testing. Users of the Profilograph devices have started utilizing the HSP as a tool to isolate operational issues from pre-existing conditions with the objective of achieving the desired contractual smoothness as a function of the rehabilitation process and lift(s) thickness of hot-mix asphalt. Case studies were undertaken on various highways in Ontario, that were undergoing Full Depth Reclamation (FDR), Cold-in-place Recycling (CIR), Expanded Asphalt Stabilization (cold in-place recycling with expanded asphalt, CIREAM) processes and conventional grind-and-pave projects. This paper outlines key lessons learned from the results of these studies, with special attention given to achievable smoothness end results as a function of the rehabilitation process. The paper also summarizes guidelines established as a result of this study to undertake profile-quality-control of various types of rehabilitation techniques outlined above. // Avec l'introduction du profilographe inertiel a haute vitesse inertielle (HSP), il est devenu possible de verifier l'uni de la chaussee avec precision et instantanement. Les HSP utilises pour tester l'uni des autoroutes en Ontario sont conformes a la classe 1 de l'ASTM, avec la capacite de mesurer l'uni de la couche de chaussee avec precision et d'une maniere reproductible. Le HSP peut fonctionner a des vitesses pouvant atteindre 80 km/h pour obtenir des resultats rapides avec une interruption minimale a la circulation pendant les essais de mesure de l'uni. Les utilisateurs des profilographes ont commence en utilisant le HSP comme un outil pour isoler les problemes operationnels de conditions preexistantes avec l'objectif d'atteindre l'uni contractuel desire en fonction procede de rehabilitation et lift(s) l'epaisseur des couches d'enrobe bitumineux a chaud. Des etudes de cas ont ete menees sur diverses routes en Ontario, qui etaient en cours de remise en etat complete a pleine profondeur (FDR), de recyclage a froid en place (CIR), de stabilisation au bitume expanse (recyclage a froid en place avec bitume expanse, CIREAM) procedes et projets de planage et pavage conventionnels. Ce document decrit les principales lecons apprises a partir des resultats de ces etudes, avec une attention particuliere aux resultats finaux d'uni realisables en fonction du procede de rehabilitation. L'article resume aussi les lignes directrices etablies comme resultat de cette etude pour entreprendre un controle de qualite du profil de divers types de techniques de rehabilitation decrites ci-dessus.

Full frame machine prediction
Teacher imitationNot 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.
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 source (direct Gemma or distilled Codex), not a consensus.
