Abstract

Expansive soil is a type of soil with significant expansion and shrinkage characteristics, posing a major threat to the stability and durability of highway subgrades. This paper reviews the impact of expansive soil on highway subgrades, explores common subgrade issues, and introduces treatment technologies for subgrades in expansive soil areas. The study shows that reasonable pretreatment, reinforcement, and drainage techniques can effectively mitigate the damage caused by expansive soil to subgrades, enhancing the service life and safety of highways.
