糠醛裂化油沥青再生剂最佳掺加比例确定

Deter mination of optimum mixing ratio of furfural cracking oil asphalt recycling agent

沥青路面老化会产生大量的废弃材料,如果能够选择合理的沥青再生剂充分利用这些废弃材料,将会节约大量的原材料和保护自然环境。利用糠醛裂化油作为沥青再生剂,通过原沥青、室内老化原沥青、掺加不同比例再生剂的室内老化原沥青室内实验室三大指标实验对比,得出最佳比例的糠醛裂化油沥青再生剂的掺加比例,再添加一些原沥青,使最佳比例再生剂的老化沥青性能达到规范要求。

Asphalt pavement aging will produce a lot of waste material, if we select reasonable asphalt recycling agent, which can make full use of the waste material and save a lot of raw materials and protect natural environment. This paper uses of furfural cracking oil as asphalt recycling agent, through indoor laboratory three index contrast experiment between original asphalt, original asphalt indoor aging asphalt and adding different proportion of recycling agent to the original asphalt indoor aging asphalt ,which can obtain the optimum proportion of furfural cracking oil asphalt ,but the best proportion of aged asphalt cannot meet standard requirements, so we need some of the original asphalt, and the best proportion can also be required by laboratory experiment.
