有机改性矿物在SMA沥青混合料中路用性能分析

Analysis in Road Performance of Activated Mineral Binder Stabilizer in SMA Asphalt Mixture

通过室内试验研究,进行断级配SMA沥青混合料路用性能验证,表明掺入有机改性活性矿物可以显著提高SMA混合料高温抗车辙、抗水损害、抗疲劳开裂等性能,同时可以节约沥青和木质素纤维用量,达到资源回收和绿色环保的目的,具有经济优势和应用价值。

Through the laboratory test and the verification of road performance with SMA graded asphalt mixture, the resultsshow that the incorporation of activated mineral binder stabilizer can significantly improve the anti-rutting property, water damage resistance and anti-fatigue cracking property of SMA mixture. At the same time, the dosage of bitumen and lignin fiber canbe saved so as to achieve the purpose of recycling waste resources and prtecting environmen, which has economic advantagesand application value.
