摘要
在评价沥青混合料的路用性能这一矛盾体时,权重是一关键因素,对方案优选起重要作用。如何相对客观地确定权重是评价模型中一个非常关键的问题。通过沥青混合料各路用性能的预估寿命这一相对客观的指标,结合比较矩阵法建立了权重模型,分别求取了沥青各面层各路用性能的权重。通过分析各路用性能的权重,可进一步指导各面层的沥青混合料的设计。
In case of assessment of the contradictory pavement performances of asphalt mixture,weight is the key factor playing important role in optimization of programme.How to confirm the weight objectively is very important for assessment model.By means of a comparative objective index,the estimated life of pavement performances of asphalt mixture and in combination with comparative matrix,the weight model is established to seek the weight of pavement performances of various asphalt layers.Through the analysis of pavement performances＇weight,the design of asphalt mixture for various layers can be further guided.
