摘要
Abstract
This study,grounded in practical maintenance projects,conducted tests on the conventional road performance and long-term durability of recycled asphalt mixtures with 25％and 40％Recycled Asphalt Mixture(RAP)content,incorporating three different recycling agents(A,B,C).The gray target decision-making theory was employed for multi-index comprehensive evaluation to optimize the RAP content and type of recycling agent.The research findings indicate that recycling agents enhance the performance of old asphalt,with vary-ing degrees of improvement among different agents.Based on a comprehensive evaluation of various perfor-mance indicators using the gray target decision-making theory,a"40％RAP content+recycling agent C"was determined as the optimal combination.This approach excels in technical performance,economic bene-fits,and environmental protection.关键词
