中文摘要：

研究了芳烃油（再生剂A）和橡胶油（再生剂B）两种再生剂对老化沥青针入度体系指标性能和流变特性的影响,分析了不同再生剂掺量下老化沥青四组分变化规律,揭示了再生剂对老化沥青的性能的恢复机理。采用拌合试验研究不同再生剂掺量下热再生混合料老化沥青砂浆的转移规律,并基于车辙试验、低温弯曲试验和控制应变疲劳试验研究了再生剂掺量对热再生混合料综合路用性能的影响。试验结果表明,再生剂与老化沥青之间有一定的配伍性,随着再生剂掺量增大,老化沥青的针入度体系指标感温性增强,低温性能提高;抗车辙因子和劲度模量均与再生剂的掺量呈良好的直线负相关;再生剂对老化沥青的影响机理在于沥青组分重新协调,再生剂的掺量应结合热再生沥青混合料路用性能试验来确定。

英文摘要：

Aromatic oils（ recycling agents A） and rubber oil（ recycling agent B） to the effects of aging asphalt penetration index and rheological properties were studied,Analysis of Variation asphalt fourcomponent of aged asphalt under different recycling agent content and recovery mechanism of the recycling agent on aged asphalt performance were revealed. Aged asphalt mortar transfer rule of hot recycled mixture were studied by using marshall mixing test,And based on the ruting test,cold bending test and Control strain fatigue test to study the comprehensive road performance of hot recycled mixture. and based on the test track,cold bending test and control studies content on hot regenerated catalyst regeneration mixture comprehensive road performance strain fatigue test Impact. The results show that there is a certain compatibility between aging asphalt recycling agent,With the recycling agent content increases,aged asphalt penetration index system temperature increased,low temperature performance improvement; dosage of anti-rutting factor and stiffness modulus and regenerated catalyst was a good negative correlation,regenerating agent the influencing mechanism of aging asphalt bitumen component is re-coordination,reasonable recycling agent content should be determined by recycling asphalt mixture performance test.
