| 摘要： | Granular surfaced roads in seasonally cold regions are frequently subjected to freeze-thaw cycles, which lead to damage such as frost heave, frost boils, thaw weakening, rutting, and potholes. The damage significantly increases maintenance costs, adversely affects public safety, and inconveniences both agricultural traffic and the traveling public. Current maintenance practice typically involves covering the entire damaged road surface with virgin aggregate and then blading without compaction, which focuses on repairing freeze-thaw damage rather than minimizing or preventing its occurrence. |
