| 中文摘要: |
| 考虑到目前评价道路沥青的相关指标，如针入度、软化点、延度等的局限性，为了更好地反映再生沥青随荷载、时间和温度变化的流变学性质，应用战略公路研究计划(strategic highway research program,SHRP)方法对3种再生沥青的路用性能进行了评价，分别从高温稳定性、中温耐疲劳性和低温抗裂性3个方面进行了分析．结果表明，再生后的沥青具有良好的高温稳定性、耐疲劳性和抗裂性，其他路用指标达到了一定的路用要求． |
| 英文摘要: |
| Thinking of the disadvantages to evaluate road asphalt with current correlative indexes, such as penetration, soft point, ductility, etc., and reflect the rheology of recycle asphalt better when the load, time and temperature change, the strategic highway research program (SHRP) was used to evaluate the in service performances of three kinds of recycle asphalt. The stability, anti-fatigue and anti-cracking at high-temperature, middle-temperature and low-temperature are analyzed. The results indicate that the performances of the high-temperature stability, anti-fatigue and anti-cracking of the recycle asphalt binder are good, and the other indexes can achieve the requirements of service. |
