AB - In order to improve the accuracy and comprehensiveness of asphalt pavement  performance evaluation, a performance evaluation model based on warm mixed  recycled asphalt pavement was proposed. Based on the evaluation indexes such  as pavement quality, pavement damage, pavement structure bearing capacity,  pavement skid resistance, pavement rutting and pavement comprehensive  performance, the performance evaluation system of warm mixed recycled  asphalt pavement was established. According to the standard numerical  characteristics of asphalt pavement performance evaluation index, the  subjection function of asphalt pavement performance is constructed. The  trapezoidal and semi-trapezoidal distribution functions are obtained, and  the membership functions of each distribution section are established.  Considering the comprehensiveness, fuzziness and complexity of the  evaluation, the fuzzy decision algorithm is introduced to determine the  interval weight of each index, and the structure is quantified according to  the evaluation index. The membership function and fuzzy subset are  established. The evaluation standard and evaluation level are determined  based on fuzzy relation matrix, and the pavement performance is evaluated.  The experimental results show that the evaluation results of this model are  accurate and reliable, and it has obvious advantages in application.
