In order to study on the influence of chloride ion on pavement performance of base material with fly-ash-flushed-by-seawater and the feasibility of fly-ash-flushed-by-seawater material used to road construction, the analysis and evaluation on the influence of chloride salt content on pavement performance of material base course are obtained through the laboratory test on pavement performance of base course with adding different content of chloride salt. The study shows that the chloride salt content in fly-ash-flushed-by-seawater influences slightly on the early strength of base course and even plays a function of early strength agent; the chloride salt content in fly-ash-flushed-by-seawater has an inhibiting effect on the growth of strength when it is more than 1.3%; the dry shrinkage coefficient increases with the aggrandizement of chloride salt content and the anti-erosion performance of material is sensitive to the chloride salt content, but temperature shrinkage coefficient and anti-freeze performance are slightly influenced by it. Fly-ash-flushed-by-seawater used to base course construction is feasible because the pavement performance of fly-ash-flushed-by-seawater base material satisfies the request of Specifications for Design of Highway Asphalt Pavement JTG D50-2006.
