Which degradation accelerates on Roman roads traversing regions with high groundwater tables?

💡 Explanation

When groundwater tables are high and temperatures drop, the freeze-thaw cycle leads to frost heaving, because water expands upon freezing, stressing the roadbed and soil destabilizing it. Therefore frost heaving results, rather than tensile cracking, iron attrition, or chemical weathering, each requiring different environmental and material conditions.
