Research on highway pavement performance management system

With the rapid development and the large investment in highway construction, the detection, evaluation, prediction and maintenance of highway pavement performance are getting more attention than ever before in today´s China. While most current codes and standards provide much guidance for the detection and evaluation of highway pavement performance, a systematic management tool to implement these provisions is rare. To fill this gap, a management system of highway pavement performance is presented. This system consists of three parts i.e. the detection subsystem which obtains the detailed data of the pavement condition by various detection tools and prepares them with specified file form, the evaluation subsystem which evaluates the pavement and categories them using scores or ranks and stores them in some databases, the prediction subsystem which predicts the status and life expectancy of the pavement based on these databases and gives maintenance suggestion for reference. This article gives emphasis to the data-processing method, interface design, database framework and total architecture of this system. The system was achieved using a combination of the programming tool and the document processing software.
