| 摘 要： | 对SBS—OGFC、干法RA—OGFC和湿法RA—OGFC三种混合料进行室内路用性能及耐久性试验。结果表明：掺加0．3％木质素纤维，SBS改性沥青和湿法生产的橡胶沥青OGFC混合料均表现出较好的路用性能和耐久性；干法生产的RA—OGFC橡胶沥青混合料部分性能达不到现行规范要求，性能较差。

| Abstract: | According to the results taken from indoor trials of pavement performance and durability of SBS- OGFC, dry- process RA -OGFC and wet -process RA -OGFC mixes, the investigation have drawn that： by admixing 0. 3 % lignin fibers, a well paving performance and durability has been achieved with SBS modified bituminous binder composition and wet -process RA -OGFC mix, some dry -process RA -OGFC mix can not meet the requirements of current specifications, to give poor road performance. |
