Preventive measures and remediation techniques for road pavement deformations in seasonal frost regions

In regions experiencing seasonal ground freezing, significant pavement deformations frequently occur, presenting substantial challenges for public road maintenance and operation. This research presents a comprehensive investigation into the mechanisms underlying these deformations and advances innovative engineering solutions for their prevention. The study examines the complex physicochemical processes within the road subgrade during seasonal freeze-thaw cycles, with particular emphasis on moisture migration patterns, ice lens formation mechanisms, and the subsequent development of structural deformations. The investigation specifically addresses the interaction between frost heave phenomena and pavement structural elements, providing new insights into the behavior of road construction materials under freezing conditions. Through extensive field observations and laboratory testing, the research has yielded enhanced design and construction methodologies specifically adapted for roadways in seasonal frost environments. The proposed engineering solutions incorporate advanced materials and construction techniques, focusing on improving long-term pavement performance while optimizing maintenance requirements. These innovations demonstrate significant potential for enhancing road infrastructure resilience and reducing lifecycle costs in cold climate regions.
