Which 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.
