This study introduces a reliability‐calibrated machine learning framework to predict the maximum dry density and optimum moisture content of heterogeneous soils. By integrating 15 algorithms with conformal prediction, the models deliver accurate compaction estimates alongside rigorous, distribution‐free 90% confidence intervals.

This review highlights how pretreatment and optimized mixture design enable the use of phosphogypsum in pavement base courses and subgrades. Combining physical, chemical, or thermal treatment with suitable binders and solid wastes can improve engineering performance, durability, and environmental safety.
