Study On The Prediction And Evaluation Of Composite Pavements Performance

As the breakage of the old cement concrete pavement in urban ,the use of asphalt concrete overlay was more and more popular .We do not have the unified standards in how. to evaluate the composite pavements service performance. Seldom studies were conducted over composite pavements in China. Therefore seldom actual test measurement datum and prediction and evaluation methods can be found. Accordingly, the author theoretically established a complex method, based on the Complex Fuzzy Evaluation Method, the Markov Chain Method and the Gray System Model, to solve the problem of performance prediction and evaluation of composite pavements. Furthermore, the algorithm of the complex method has been realized by mixed VC++ and Fortran95 Programming.The author study on Complex Fuzzy Evaluation and prediction Method as follow: The choice of the evaluation index ; The conversion of the hundred-mark system of the evaluation index ;How to make use of Seldom data to predict single index value; How to make use of Gray System Model and Markov Chain Method in the complex fuzzy evaluation and prediction.The first chapter of the article is exordium, introduce the purpose of study the composite pavements, this chapter also introduce the desire method of the composite pavements. Chapter 2 introduce the require of service performance,breakage styles of the composite pavements,the choice and survey of the composite pavements. In Chapter 3 and Chapter 4 the author study the method of evaluation and prediction used in this article. In Chapter 5 the algorithm of the complex method has been realized by mixed VC++ and Fortran95 Programming. In the last chapter the author use the actual measurement datum to certificate the feasibility of the method and the accuracy of the Programming.Pass the above calculation and analysis, this paper can get a conclusion, adopt a complex fuzzy method in evaluation and prediction of composite pavements is feasibility.
