[Abstract]:The expressway links all areas of the national economy with each area closely. It plays an important role in promoting economic development, promoting cultural exchange and promoting social progress. The performance of pavement is one of the most important functions of the highway. It is necessary to ensure that the expressway is safe, economical and efficient. Management and maintenance. The correct evaluation of pavement performance is one of the important bases for making maintenance and maintenance plan and making investment decision. It is an important part of pavement maintenance management system. Therefore, the research on pavement performance evaluation method is greatly emphasized at home and abroad, and it is a hot topic in the field of road engineering. One of the questions.
At present, the correlation of four kinds of pavement performance evaluation methods commonly used at home and abroad is not very ideal, the objectivity of the system analysis method is not strong, the grey theory method has certain subjective empiricism, and the other methods are still in the study stage, and these methods are based on the common highway and high speed public. The road has the characteristics of heavy traffic, truck axle load, traffic channelization and high speed, and the characteristics of pavement performance and the law of development and change are quite different from that of ordinary highway. Therefore, the research on the new method of evaluating the performance of highway pavement performance is very important to ensure the smooth transportation of roads and the smooth development of the national economy. Important theoretical and practical significance.
In view of these problems, based on the analysis of the existing evaluation methods of the existing asphalt pavement performance, this paper makes a thorough research on the performance evaluation of the expressway asphalt pavement performance. The concrete results of this paper are as follows:
1, the current situation of pavement performance evaluation methods at home and abroad is reviewed, the basic ideas and advantages and disadvantages of various evaluation methods are discussed in detail, and the development trend of pavement performance evaluation is discussed in depth, which provides the basis and reference for the establishment of new evaluation methods.
2, the characteristics of expressway asphalt pavement are analyzed, and the commonly used evaluation indexes of pavement performance are studied. According to the characteristics of the expressway, the indexes are improved, and some evaluation indexes which can fully reflect the performance characteristics of expressway asphalt pavement are discussed.
3, in view of the advantages and disadvantages of genetic algorithm and neural network, the necessity and feasibility of combining GA with NN is discussed, and a hybrid GANN model which can give full play to the advantages of genetic algorithm and neural network is established, and a hybrid GANN model is realized by selecting simple, efficient and open Matlab language.
4, a hybrid GANN evaluation method for expressway asphalt pavement performance is put forward for the first time.

Evaluation of expressway asphalt pavement performance; evaluation of Hubei section of Beijing Zhuhai expressway.
The results show that the method is accurate, scientific, efficient and practical, and the evaluation process is convenient, fast and forecast.
Scientific and accurate;
5, a hybrid GANN prediction method for asphalt pavement condition index PCI is put forward for the first time.
Methods the mixed GANN model was applied to pavement roughness, strength factor 551 and skid resistance SFC.
Based on the measured data, the model is established, and the prediction of pavement condition index PCI is realized.
The method can conduct a targeted investigation of the road surface damage, reduce the scope of investigation, and save manpower and material resources.
Improve work efficiency.
This research project has been studied in Hubei province.
