Study on Comprehensive Post Evaluation of Hot in Place Recycling Project Based on AHP-SA-FCE Model

Abstract

Because of its incomparable advantages, the hot in place recycling technology has been widely used in recent years, but its completion rate is only about 80% every year. In this paper, the pavement performance, economy, environment and society as the starting point, the hot in place recycling project is analyzed and evaluated. This paper relies on the AHP-SA-FCE evaluation model. It is an evaluation which combines AHP, SA and multi-level fuzzy comprehensive evaluation (FCE) together to learn from each other's strengths and overcome each other's weaknesses. Its theoretical basis is to apply fuzzy mathematics to system evaluation, and to achieve the evaluation object from qualitative to quantitative analysis process. According to AHP-SA-FCE model, the result of fuzzy comprehensive evaluation of the hot in place recycling project is B =（0.2941，0.2838，0.2325，0.1616，0.0354). The ratio of the results in the "very successful" range is 0.2941, the ratio in the "successful" range is 0.2838, and the sum of the two parts is 0.5779. Visible, the hot in place recycling project was completed successfully.
