摘要
通过对韩国SK沥青和壳牌沥青,分别掺入T161B和4303星型改性剂以及YH1301-1和1320-115线性改性剂,制备出SBS改性沥青,深入的分析了改性沥青各项性能随SBS掺量的变化规律。结果表明:改性剂掺量为4.4%的时候,改性沥青各项性能达到了最优,而且SBS改性剂掺量超过了4.8%的时候,其低温延度就会下降。
The excellent performance of SBS modified asphalt deriving from the SBS modifier,therefore the SBS dosage of modified asphalt directly determine its performance.The test of SK90# asphalt and Shell90# asphalt,respectively incorporated SBS modifier of YH1301-1,4303,T161B and 1320-115 prepare SBS modified asphalt.By the in-depth analysis and exploration the performance of modified asphalt with SBS dosage variation,the results show that when modifier content is 4.4%,its performance to optimize; when SBS modifier dosage more than 4.8%,its low-temperature will to drop ductility.
