Abstract

Abstract: Four kinds of the processing temperatures (160,170,180,190 ℃) and three kinds of the storage temperatures（90, 120,150 ℃）, which were in different range, were selected to process and store the different SBS modified asphalt (E+S-YS, E+S-YY, S+S-YY). The temperature sensitivity, high temperature performance and low temperature performance were analyzed by asphalt experimentation and repeat creep test. The results show that the different processing and storage temperatures affect the performances of three kinds of SBS modified asphalt differently. When the processing temperature is 180 ℃ and the storage temperature is 150 ℃, the various performances of S-YY modified asphalt achieve the optimal effect; while the processing temperature is 170 ℃ and the storage temperature is 120 ℃, the various performances of S-YS modified asphalt achieve the optimal effect. The recommended value of the processing and storage temperature for enhancing the performance of different SBS modified asphalt was proposed.

Key words: road engineering;SBS modified asphalt, processing temperature, storage temperature, performance

摘要： 选取4个加工温度（160，170，180，190 ℃）与3个存储温度（90，120，150 ℃）对3种SBS改性沥青（E+S-YS，E+S-YY，S+S-YY）进行改性加工与存储；应用沥青常规试验与重复蠕变试验，进行了感温性、高温性能、低温性能的试验研究。研究结果表明：不同的加工温度与储存温度，对3种SBS改性沥青的性能影响不同，当加工温度为180 ℃、存储温度为150 ℃时，S-YY 改性剂的改性沥青各项性能达到最优；当加工温度为170 ℃、存储温度为120 ℃时，S-YS改性剂的改性沥青各项性能达到最优。针对不同类型的SBS改性沥青提出相应的制备与存储的温度推荐值。
