Field investigation of granular base rehabilitation project incorporating a woven geotextile separation layer, sand, and cement stabilization
Bibliographic record
Abstract
Full-depth reclamation and cement strengthening has been used successfully to dry and strengthen granular pavements. However, some thin pavements fail due to severe wetting-up of the subgrade, thus requiring additional substructure strengthening and (or) drainage systems. This research investigated the laboratory characterization and in situ field mechanical behaviour of full-depth reclaimed and cement-stabilized granular materials in conjunction with a woven geotextile and sand drainage system. This research showed that the integration of cement-stabilized reclaimed granular materials with a geotextile separation layer and sand drainage system significantly improved the mechanical primary response and climatic durability properties of the reclaimed road structure. The cement-stabilized and geotextile separation–drainage system improved the structural asset management test results from a completely failed road structure to primary plus load-carrying capacity. This research also demonstrated an improved correlation between the mechanistic material constitutive properties of the stabilized aggregate to the end-product field structural assessment relative to conventional California bearing ratio and unconfined compressive strength test results.

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.
