摘要

In order to study on key technical index for construction of base course with fly-ash-flushed-by-seawater stabilized crushed-stones, starting with the laboratory tests, through the construction and monitoring of test road, the paper obtains the key techniques for construction of base course with fly-ash-flushed-by-seawater stabilized crushed-stones. Through tracing detection to the construction of test road, various index signs all satisfy the requirements of norm. Through the long-term monitoring of test road, pavement performances such as deflection display normally. This paper recommends the best mixture ratio of cement-fly-ash-flushed-by-seawater stabilized crushed-stones: the cement: fly-ash-flushed-by-seawater: stone = 5:10:85. The moisture content should be controlled at 4.5% to 7%. The dry density should be controlled at 2.2-2.3 g/cm~3. If the key technical index in construction is controlled seriously, the fly-ash-flushed-by-seawater used in base course construction is feasible.
