摘要:
为了实现废橡胶为原料制备的再生剂用于废旧沥青混合料的再生,分别对路面抽提回收的老化沥青及废旧沥青混合料进行了再生试验,通过老化沥青及混合料性能的指标恢复情况探讨利用废橡胶进行沥青混合料再生的可行性,并进行了作用机理分析.结果表明,利用废橡胶微波处理制备的再生剂对老化沥青具有改性作用,可以有效恢复其各项流变性能,再生剂添加量为10%左右的再生沥青针入度、软化点、延度和低温劲度都接近基质沥青指标;再生沥青混合料的高低温性能、水稳性以及抗老化性能都能满足沥青路面的技术要求.
Abstract:
In order to realize the regenerative prepared from waste rubber as raw material for the recycling of waste asphalt mixture, the recycling test of aged asphalt and waste asphalt mixture recovered from pavement extraction was carried out, and the feasibility of using waste rubber for asphalt mixture regeneration was discussed through the recovery of the performance of aged asphalt and mixture, and the mechanism of action was analyzed. The results show that the recycler prepared by microwave treatment of waste rubber has a modifying effect on the aging asphalt, which can effectively restore its rheological properties, and the penetration degree, softening point, ductility and low-temperature stiffness of the recycled asphalt with the addition of recycler amount of about 10% are close to the matrix asphalt index. The high and low temperature performance, water stability and anti-aging performance of recycled asphalt mixture can meet the technical requirements of asphalt pavement.
