← ScienceWhich outcome results when moisture freezes within asphalt?
A)Pothole formation through cryofracture✓
B)Viscosity increases, resisting plastic flow
C)Decreased thermal expansion coefficient
D)Reduced tire adhesion via hydroplaning
💡 Explanation
Potholes form, because cryofracture occurs as ice expands. The expansion exerts pressure exceeding asphalt tensile strength; therefore cracking occurs rather than increased viscosity or decreased thermal expansion which require distinctly different mechanisms.
