摘　　要：为了研究泡沫温拌技术对SBS改性沥青混合料的影响,从SBS泡沫沥青的制备参数、混合料适宜的压实温度以及路用性能进行系统性的分析.试验结果表明,发泡时SBS改性沥青加热温度为170℃,用水量为沥青总量的3%;SBS泡沫温拌沥青混合料适宜的成型温度为150℃;SBS泡沫沥青混合料的高温性能和水稳定性与常规热拌沥青混合料的高温性能相当,低温性能略低但满足规范要求.SBS modified asphalt was selected for the preparation of FWMA, the suitable foaming and compaction conditions as well as pavement performance of FWMA were systematic studied to research the effects of foamed warm-mix technology on SBS modifies asphalt mixture. The proper foaming condition for SBS modified asphalt is determined as 170℃ with 3% water content, and the optimum compaction temperature for FWMA is 150℃. Becides, test results indicate that FWMA generally exhibits the same high temperature performance and moisture stability as HMA. However, its low temperature performance is a bit worse than HMA but can still meet the specification requirements .
