Research　on　impact　of　climate　on　highway　requires　climatic　evaluation　indicators　to　describe　or　to　evaluate　climate　processes　and　climate　conditions　impacting　highway.　Research　on　climatic　evaluation　indicators　for　highway　is　conducted　to　fulfill　this　requirement.　Through　analysis　of　characteristics　of　climate　processes　and　climate　conditions　prominently　impacting　highway,　evaluation　indicators　for　solar　radiations,　high-temperature　process,　low-temperature　process,　freeze-thaw　cycle,　moisture　condition,　dry-wet　cycle,　process　of　high　temperature　with　moisture　or　precipitation,　process　of　freeze-thaw　cycle　with　moisture　or　precipitation,　extremely　low　temperature　are　constructed　respectively.　Indicators　evaluating　impact　of　climate　on　highway　construction　are　also　given.　Then,　system　of　climatic　evaluation　indicators　for　highway　is　built,　which　provide　references　for　research　on　impact　of　climate　on　highway.
