Decision-Making for Typical Pavement Structure Based on Life-Cycle Economic Evaluation and Key Performance Indicators

The economy and rationality of the typical structural scheme for asphalt pavement are directly related to formation its service target. Based on original highway structure in Jilin Province, evaluation index system was established by research literature, investigation Delphi method, results expert consultation were tested indicators such as enthusiasm, authority coordination. Kendall coordination coefficient 0.803, indicating a strong degree consistency. Then, using finite element method economic analysis key parameters asphalt, design performance calculated. Finally, process quantified analytic hierarchy (AHP) gray relational theory, weight each indicator correlation calculated, 1 is determined be best solution. show that decision model types can an improved process. In this study, decision-making quickly conveniently determine most suitable structure, selected structures checked, calculation meet requirements specification. However, given limited reference cases, proposed needs verified through more practical applications.
