Embodiment Construction

[0052] The technical solutions provided by the present invention will be fully described below in conjunction with specific embodiments. Apparently, the described embodiments are only some examples of the present invention, not all examples.

[0053] Fuzzy comprehensive evaluation method is a comprehensive evaluation method based on fuzzy mathematics. This method can transform qualitative evaluation into quantitative evaluation, and AHP is an analysis method for multi-objective decision-making. This method can perform pairwise comparison of multiple index factors to determine the weight of the index. Therefore, the combination of AHP and fuzzy comprehensive evaluation method to evaluate the existing service quality of asphalt pavement ensures the correctness of the evaluation results, and is of great importance for accurately judging the timing of asphalt pavement maintenance and studying the decline law of the existing service quality of asphalt pavement. Guiding significan...

Abstract

The invention discloses an evaluation method for the existing use quality of an asphalt pavement. The method comprises the following steps: selecting an asphalt pavement on which the existing use quality is to be evaluated; according to an existing standard basis, analyzing and selecting an existing use quality evaluation index of the asphalt pavement; determining the selected existing use quality evaluation indexes as a factor set of a multi-level fuzzy evaluation method; according to the principle of a multi-level fuzzy evaluation method, determining a comment set for evaluating the existing use quality of the asphalt pavement; and performing matrix synthesis operation on the weight matrix and the multi-level fuzzy comprehensive evaluation matrix to obtain a fuzzy vector of multi-level fuzzy evaluation of the existing use quality of the asphalt pavement, and evaluating the existing use quality of the asphalt pavement based on the fuzzy vector. According to the invention, the multi-level fuzzy evaluation method is adopted to evaluate the existing use quality of the asphalt pavement, a new method is provided for evaluating the existing use quality of the asphalt pavement, and meanwhile, the method has important guiding significance for accurately judging the maintenance opportunity of the asphalt pavement.

Description

technical field [0001] The invention relates to a method for evaluating the existing service quality of asphalt pavement. Background technique [0002] Asphalt pavement composed of asphalt materials has become the main form of high-grade pavement in my country due to its excellent performance. However, with the continuous development of my country's road transportation industry in recent years, the traffic load carried by asphalt pavement is increasing, and the existing quality of asphalt pavement caused by traffic load and other environmental factors continues to decline. The decline in the quality of asphalt pavement will directly affect the driving comfort and safety of asphalt pavement. It is the key to ensure the existing quality of asphalt pavement to regularly and reasonably and accurately evaluate the existing quality of asphalt pavement. [0003] At present, the evaluation of the existing service quality of asphalt pavement is calculated and evaluated through the ...
