How does frost action cause weathering

WebMay 6, 2024 · Weathering is the process that changes solid rock into sediments. Sediments were described in the Rocks chapter. With weathering, rock is disintegrated. It breaks into pieces. Once these sediments are separated from the rocks, erosion is the process that moves the sediments. Erosion is the next chapter’s topic. WebFrost action divides into two phases: freezing the soil water, and thawing the soil water. For pavements, frost action becomes critical when either (1) the freezing phase is accompanied by noticeable heaving of the road surface, or (2) the thawing phase is accompanied by a noticeable softening of the roadbed.
