摘　　要：再生改善剂与老化沥青渗透融合能力决定了老化沥青性能的改善效果,直接影响到再生混合料的性能。通过针入度试验和化学组分变化试验从温度、时间和种类研究再生改善剂与老化沥青渗透融合能力。结果表明,在一定范围内提高温度和延长时间能够提高再生改善剂与老化沥青的渗透融合能力,再生改善剂一定程度上能够改变老化沥青化学组分,DYZH型再生改善剂具有良好的渗透融合能力。Combination between recycling agent and aged asphalt affects performance of aged asphalt and recycled mixture. The article conducts a studying on combination between recycling agent and aged asphalt through penetration and chemical composition which consider temperature, time and species. The results show that raising temperature and time can improve combination ability between recycling agent and aged asphalt, and recycling agent can changes chemical composition of aged asphalt. Type DYZH recycling a- gent has good combination ability.
