The Gray Superiority Analysis of Asphalt Pavement Performance Evaluation Index and Main Diseases

Based on field observations, determine the main diseases of asphalt pavement in China. According to existing evaluation theories and methods, apply the gray superiority theory to analyze indicators of the surface performance and main diseases of asphalt pavement, which means to determine the relativity between pavement performance indicators and main diseases, The conclusion shows that it has a certain significance to improve the detection efficiency and to provide theoretical basis for establishing evaluation model which uses the main diseases as the index.
