摘　　要：以固硫灰作为路面基层材料,研究了固硫灰原灰和经预处理固硫灰路面基层材料的最佳含水量、最大干密度、体积安定性、膨胀率和强度等性能。同时,通过重金属浸出实验评估了固硫灰对土壤环境的影响。结果表明,经预处理固硫灰路面基层材料体积安定性好,膨胀率低,性能良好;此外,固硫灰重金属浸出率低,符合环保要求。Circulating fluidized bed combustion ashes （FBCF） were used as road base materials. The properties of original and pretreated FBCF road base materials were studied. And the influence of heavy metal of FBCF on the soil was also researched through leaching experiments. Results show that high volume stability, low inflation rates and the better road performance were obtained when pretreated FBCF was used. In addition, FBCF road base materials have lower heavy metal leaching rate, which in line with environmental protection require- ments.
