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.
