Influence of Warm Mix Agent on the Road Performance of Rubber Modified Asphalt
The utilization and progression of warm-mixed asphalt mixture and rubber modified asphalt mixture in China have been im-pressively rapid.The amalgamation of these two technologies results in a mutually advantageous complementation of superior road per-formance and construction performance,while simultaneously providing advantageous energy-saving,emission reduction,and green en-vironmental 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 rub-ber modified asphalt and its mixture were analyzed and studied.It was determined that warm-mixed additives can mitigate the temper-ature sensitivity of rubber modified asphalt,ameliorate the low-temperature rheological properties and durability of rubber modified as-phalt,and effectively enhance the high and low-temperature stability of rubber modified asphalt mixture.
