研究了Evotherm温拌SBS改性沥青,结果表明,Evotherm温拌剂对SBS改性沥青性能影响不大.采用旋转压实和马歇尔击实对Evotherm温拌SBS改性沥青混合料性能进行研究,研究结果表明,Evotherm温拌SBS改性沥青混合料碾压温度可较热拌沥青混合料降低20℃～30℃左右.温拌混合料的水稳性能较热拌沥青混合料有所提升,浸水马歇尔残留稳定度从93.5％提高到95.2％,冻融劈裂试验强度比从83.8％提高到86.4％；高温稳定性能有所提升,车辙试验动稳定度从7 314次/mm提高到8 023次/mm;低温抗裂性能变化不大.总体来说,击实温度145℃的温拌沥青混合料性能优于热拌沥青混合料.%This paper research the Evotherm SBS modified asphalt, the results show that, Evo-therm has little Influence on SBS modified asphalt. Using rotary compaction and Marshall compaction to research characteristic of Evotherm warm mix asphalt. Research results show that, Evotherm warm mix asphalt compaction temperature can reduce 20 ~ 30 ℃ compared with hot mix asphalt. Warm mix asphalt water stability was improved compared with hot mix asphalt, Marshall immersion residual stability increased from 93. 5% to 95. 2% , freeze-thaw splitting test intensity ratio increased from 83. 8% to 86. 4% ; high temperature stability performance has the promotion, rutting test dynamic stability from 7 314 time/mm to 8 023 time/mm; low temperature resistance performance changed little. Over all, Performance of warm mixed asphalt compacted in 145 t is better than that of hot mix asphalt.
