越南F1赛道专用SBS改性沥青研究

Study On Special SBS Modified Asphalt For F1 Tracks In Vietnam

通过采用选定的SBS改性剂A、相容剂B和稳定剂C,对选定的四种基质沥青进行改性沥青制备试验,确定越南F1赛道专用SBS改性沥青的基质沥青和最优改性制备方案。对采用最优方案制备的越南F1赛道专用SBS改性沥青进行常规性能及MSCR试验评价,结果表明其具有优良的抗老化性能、稳定性能、高温抗变形能力和弹性恢复性能,高温路用性能和弹性恢复能力尤其突出,适合铺筑越南F1赛道。

Selecting SBS modifier A,compatibilizer B,stabilizer C and four matrix asphalt to prepare modified asphalt,to determine the matrix asphalt and optimal modified formulation of special SBS modified asphalt for F1 tracks in Vietnam.By conventional performance and MSCR test,it show that SBS modified asphalt prepared by optimal formulation for Vietnam F1 tracks,has excellent aging resistance,stability,high temperature deformation resistance and elastic recovery performance.The outstanding high temperature performance and elastic recovery ability are especially excellent and suitable for paving Vietnam F1 tracks.
