| 摘 要： | 厂拌热再生作为当前应用最为广泛的沥青路面再生技术,RAP掺加比例普遍较低。将温拌技术和再生技术相结合,对基于温拌的高掺量厂拌热再生混合料的配合比设计以及混合料的性能进行研究,并指导实体工程施工。结果表明,温拌剂Evotherm可提高老化沥青的性能,40%RAP+Evotherm再生混合料Sup-20的路用性能均符合技术要求,且表现出更好的高温抗车辙变形能力。高掺量温拌再生技术在S325省道的成功应用,为类似工程提供借鉴和参考。

| Abstract: | Plant mixing heat regeneration,as the most widely used asphalt pavement regeneration technology,in which the RAP content is generally low.In this paper,we study the mix proportion designand the performance of mixture performance by combining the warm mixing and regeneration technology,and direct construction engineering.The results show that the warm mixing agent Evothermimprove the performance ofaged asphalt.The road performance of regeneration mixture Sup-20,40%RAP mixed with agent Evotherm,meets the technical requirements and shows better high temperature rutting resistance.The successful application of high content warm mixing regeneration technology in S325 provincial road provided a reference for similar projects. |
