In order to significantly improve the recycling efficiency and recycling capacity of the re-cycled asphalt pavement material(RAP),and maximally meet the future demand for large-scale recy-cling of the RAP material,this paper firstly analyzes the influence of traffic volume,applicable layer,damage type and quality of RAP material on the applicability of recycling technology,and constructs different recycling technology collaborative implementation decision-making models for highways and ordinary mainline highways by using the analytic hierarchy process(AHP).Meanwhile,it also pro-poses multi-objective collaborative recycling technology applicability analysis process,which realizes the planning of pavement recycling technology for different maintenance needs.The corresponding col-laborative recycling maintenance schemes are proposed based on Xiyi Expressway,analyzing the eco-nomic and environmental benefits of different recycling schemes,and establishing a collaborative recy-cling maintenance technology evaluation model based on the improved random forest algorithm.The case study clearly proves the rationality and applicability of the decision-making method applied in this study.
