melting point of a solvent?????????
i think it's boiling point not melting point
chemvijay is right.

jfraser · Answer

both melting and boiling points are affected by the addition of a solute to a solvent. Boiling points are elevated, and melting points are lowered. That's why salt is put on icy sidewalks in winter

Your answer is partially correct , but - 
NaCl (aq) would destroy the surrounding living environment @JFraser , as is proved when the tide comes in further than normal .(ex. Super Storm Sandy) . Therefore CaCl is used instead , the calcium chloride actually provides nutrients to the surrounding living environment and acts as a fertilizer.

I never said "table salt", but $CaCl_2$ is the salt used for sidewalks, not $NaCl$
