热再生路面病害分析及Mtn就地热再生施工技术研究
Analysis of Pavement Diseases Caused by Thermal Regeneration and Research on On-site Thermal Regeneration Construction Technology for Mtn
摘要
Abstract
In this paper,the surface layer diseases of K291+250-K315+085 Xinyuan Expressway in Hebei province and the technical indicators of thermal regeneration pavement were statistically analyzed,and the key technical points of geothermal regeneration construction were summarized.the special maintenance project on the upper layer of the highway can adopt the geothermal regeneration construction technology,make full use of waste milling material,by adding 5％～7％(the content of regenerator is 5％～7％of the asphalt content in the milling waste)Mtn modified regenerator,20％newly mixed modified asphalt mixture(the blending ratio of milling material and new additive is mill-ing material:new additive=80:20),through the heating unit heating,so that after the"field process-ing"of the new asphalt mixture to meet the technical requirements of road upgrading.After paving and compacting,the overall quality of the road reaches the qualified standard and meets the traffic conditions.the construction technology is mature,safe and reliable,energy saving and environmental protection,meets the national requirements of low carbon and economy,and provides construction reference and basis for the special maintenance of highway pavement geothermal regeneration technology.关键词
