Abstract:
According to the survey, the pavement of the high-speed bus stations suffered from several failures due to heavy traffic on heavy vehicles and frequent traffic and heavy loads on it. The present study aims to provide a mathematical relationship based on the variables affecting the pavement status index. In fact, the purpose of this research is to collect data on the failure of a number of railway stations in Tajrish based on the data available in the municipality of Tehran and to present a mathematical model for its performance in terms of failures, ultimately providing a rational solution for its repair. . In this research, statistical models for modeling as well as statistical tests will be used to validate the results. The methodology of this research includes the study of literature and its theoretical foundations, as well as previous studies on pavement failures and its repair methods for bus lines and its stations, and studies on the present research, collecting data related to the failure Data analysis and statistical analysis are based on the variables, using regression and logarithmic models and SPSS software, validating the results and conclusions and suggestions. The results of the research showed that the proposed models have the ability to predict the position of the pavement and determine it on the basis of effective variables in a rapid manner and operate according to their independent variables. The results showed that in the studied models, based on the coefficients of each of the effective variables, it can be concluded that the effect of loading and loading frequency has the most effect on the pavement failure index, after which the traffic flow, the density of failure, density and The failure type and decay factor are effective on the dependent variable of the pavement index, respectively. At the end of the research, based on the determined pavement status index of the proposed relationships, as well as pavement breakdowns, the repair and maintenance methods for each station were dealt with.
