摘要
温拌沥青混合料与橡胶改性沥青混合料在国内的应用发展十分迅速,两项技术结合可以在路用性能、施工性能方面实现优势互补,并具有节能减排、绿色环保的优势。为探讨温拌剂对橡胶改性沥青路用性能的影响,以60目废旧轮胎胶粉、盘锦90#沥青、国产LKW-Ⅱ型温拌剂制备改性沥青,通过室内试验,分析研究温拌剂对橡胶改性沥青及其混合料性能的影响。确认温拌剂能够降低橡胶改性沥青的温度敏感性、改善橡胶改性沥青的低温流变性及其使用耐久性,并有效提升橡胶改性沥青混合料的高低温稳定性。
The utilization and progression of warm-mixed asphalt mixture and rubber modified asphalt mixture in China have been impressively rapid.The amalgamation of these two technologies results in a mutually advantageous complementation of superior road performance and construction performance,while simultaneously providing advantageous energy-saving,emission reduction,and green environmental benefits.To explore the effects of warm-mixed additives on the road performance of rubber modified asphalt,60 mesh waste tire rubber powder,Panjin 90#asphalt,and domestically produced LKW-II warm-mixed additive were implemented in the preparation of modified asphalt.By conducting indoor experiments,the influence of warm-mixed additives on the performance of rubber modified asphalt and its mixture were analyzed and studied.It was determined that warm-mixed additives can mitigate the temperature sensitivity of rubber modified asphalt,ameliorate the low-temperature rheological properties and durability of rubber modified asphalt,and effectively enhance the high and low-temperature stability of rubber modified asphalt mixture.
