Evaluation of Expressway Asphalt Pavement Performance Based on the Fuzzy Theory

摘要

To more scientific evaluation of asphalt pavement performance, provide maintenance decision objective, accurate and comprehensive data, based on the fuzzy comprehensive evaluation method evaluation, this paper constructs the high grade highway asphalt pavement performance evaluation model. This paper is from four indicators of the pavement condition index, the structure strength index, driving quality index and lateral force coefficient to build the evaluation system, then establishes membership function and calculates the weight, then performance level is calculated by the maximum membership degree comprehensive evaluation method, finally through the actual case evaluation, the results show that the model can effectively solve the problem of high grade highway asphalt pavement performance evaluation.
