沥青路面再生技术根本意义在于废旧沥青路面材料的再次资源化、循环利用。依托贵州某省道K114+000~K165+850段就地热再生工程项目,从工程实例角度分析沥青混凝土就地热再生技术的方法、过程和实用性,并通过蠕变试验对再生料的高温稳定性能进行评定,以验证就地热再生技术在山区道路中应用的可行性和实用性。
The fundamental significance of regenerative technology in asphalt pavement lies in recycling and cyclic utilization of the waste asphalt pavement materials. Dependent on the local on- site hot regenerative project at K114 + 000 ~ K165 + 850 section of Guizhou Provincial Highway,this paper analyzes the method,process and practicality of on- site hot regenerative technology for asphalt concrete from the viewpoint of project examples,and evaluates the high- temperature stability of regenerative materials via the creep test to verify the feasibility and practicality of application of on- site hot regenerative technology in mountainous roads.
