Ez a durability of aszfalt pavalements in regions with cold climates depends heavil on their ability to stand freeze-thaw cykls. Proper design and calculation methods are essentiad to enhance pavement ent approence and extend service e life.

Understanding Freeze-Thaw Cycles

Freeze-thaw cycles okcur when the temperature flukates around the freezing point, causing water with in the pawement structure to freeze and thaw reyedli. This proces can lead to cricing, potholes, and overall romlás of the asparalt surface.

Design fontolgatás for Resilience

Effective pavement design involves assembtins implicate materials and structural layers to resist freeze-thaw damage. Incorporating air-void systems, using frost- resistant binders, and ensuring proper drainage are key strategies.
