摘要
研究了橡胶粉和高模量剂掺量对SMA混合料综合路用性能的影响,并将其与SBS改性SMA混合料进行对比,采用双因素方差分析法研究了橡胶粉和高模量剂掺量变化对复合改性沥青混合料路用性能的影响。试验结果表明,基于橡胶粉与高模量剂复配技术所生产的SMA混合料,其综合路用性能可达到甚至超过SBS改性SMA混合料,该复合方案具有较好的技术优越性。
The effect of rubber powder and high-modulus agent on general pavement performance of SMA mixture was studied and compared with that of SBS modified SMA mixture.Two-factor variance analysis method was applied to study the pavement performance of composite modified asphalt mixture affected by the mixing amount of rubber powder and high-modulus agent.Rubber powder and high-modulus agent modified asphalt mixture is proven to be advantageous in general pavement performance against SBS modified SMA mixture.
