Effect of Temperatures on the Dynamic Properties of Asphaltic Core for an Earth Dam
Bibliographic record
Abstract
Asphaltic concrete has been used as impervious core in embankment dams because it can be built quickly and efficiently even in areas with high precipitation in contrast to embankment dam with clay or till cores. In this study, a series of resonant column tests were conducted on asphaltic concrete samples to investigate the effects of temperature on dynamic properties for different confining pressures. Samples were tested at the temperatures of 0, 5, 10, 15, and 22°C. Technique used to conduct temperature controlled testing in resonant column test is presented. Resonant column testing at each temperature was performed at three confining pressure of 50, 150, and 350 kPa. Effect of confining pressure variation on dynamic properties of asphaltic concrete samples is negligible. However, shear modulus and shear wave velocity change significantly as a function of temperature; For instance, as the temperature increases from 0 to 22°C, the shear modulus and shear wave velocity decrease approximately 25% and 13%, respectively.

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.
