← ScienceWhich consequence results from thermal stress fracturing road surfaces treated with de-icing NaCl?
A)Osmotic pressure weakens asphalt matrix
B)Cation intercalation hinders crack propagation
C)Accelerated corrosion of steel reinforcement✓
D)Anion-induced asphalt oxidation catalysis
💡 Explanation
Steel reinforcement is susceptible to corrosion because the *electrochemical attack* from chloride ions creates oxidation; therefore, the steel weakens the road structure, rather than asphalt damage, because of accelerated electron transfer.
