Title: Test Research on Evotherm Warm Mix Asphalt Performance
Abstract: This paper research the Evotherm SBS modified asphalt,the results show that,Evotherm 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 7314 time/mm to 8 023 time/mm;low temperature resistance performance changed little.Over all,Performance of warm mixed asphalt compacted in 145 ℃ is better than that of hot mix asphalt.
