橡胶沥青SMA混合料路用性能的试验研究

摘要

Through the comparative experiments on high temperature anti-rut capacity, low temperature anti-crack capacity, water stability and aging resistance of SMA mixtures of rubber asphalt and SBS modified asphalt, the pavement performance of SMA mixture of rubber asphalt is analyzed.The results show that: compared with SMA mixture of SBS modified asphalt, the low temperature anti-crack capacity and aging resistance and so on of SMA mixture of rubber asphalt improve, and high temperature anti-rut capacity and water damage resistance are near.%通过对橡胶沥青、SBS改性沥青SMA混合料的高温抗车辙能力、低温抗开裂能力及水稳定性、抗老化能力的对比试验,分析了橡胶沥青SMA混合料的路用性能,结果表明:橡胶沥青SMA混合料与SBS改性沥青SMA混合料相比,低温抗裂能力、抗老化能力等有所提高,高温抗车辙能力、抗水损害能力相近.
