为研究温拌剂和阻燃剂对 SBS改性沥青性能的影响以及温拌剂和阻燃剂的交互作用,选用2种温拌剂(Sasobit,EWMA-1)和2种阻燃剂(FRMAXTM高效型,Sasoproof),各自掺量为 Sasobit 3%, EWMA-17‰,FRMAXTM7%及Sasoproof 6%.采用三大指标测试法、氧指数试验法、PG分级方法及布洛克菲尔德粘度计法,分别测试了不同类型沥青的三大指标、极限氧指数、路用性能指标(高、中、低温)及表观粘度.试验结果表明:Sasobit温拌剂对 SBS 改性沥青的高温性能有利,对其低温性能不利;EWMA-1温拌剂则相反.阻燃剂不利于温拌沥青的低温性能,但它可以提高 SBS改性沥青的阻燃性能.而温拌剂在大幅度降低 SBS改性沥青的施工高温粘度...

In order to study the influence of warm mix agents and flame retardants on road performance of SBS modified asphalt,and the interaction between warm mix agents and flame retardants,two kinds of warm mix agents (including Sasobit,EWMA-1)and two kinds of flame retardants (including FRMAXTM,Sasoproof)were selected.Their re-spective amounts are Sasobit 3%,EWMA-1 7‰,FRMAXTM7%,Sasoproof 6%.Three index test method,oxygen index test method,PG grade method and Brookfield viscome-ter method were used correspondingly to test the three index,limit oxygen ...
