Abstract
Accurate evaluation and analysis of expressway pavement performance is a prerequisite for determining the pavement design scheme and maintenance scheme. Due to the fuzziness and randomness of many factors affecting the pavement performance, this paper relies on the reconstruction and expansion project of Xinglin section of the Taihang mountain expressway, a method of highway pavement performance evaluation based on fuzzy mathematics is proposed. The results show the following: ① the study uses the factor domain, the comment level domain, the fuzzy relationship matrix, the evaluation factor full vector, and the fuzzy comprehensive evaluation result vector five-step method. The method can be effectively combined with the multi-index comprehensive detection index used in the specification. ② Based on the multi-index comprehensive test and evaluation adopted in the specification, the performance grade of the old road surface was quantitatively evaluated by the iterative calculation of fuzzy mathematics that broke through the evaluation mode which was based on the traditional detection methods. The research results provide innovative theoretical methods for the accurate evaluation and analysis of highway pavement performance in the semiarid climate region and also play a technical supporting role for the pavement design scheme and maintenance scheme decision-making in the semiarid climate region.
Highlights
By the end of 2017, the total mileage of expressways in China is close to 130,000 km, among which the service period of 5–10 years accounts for up to 45%. e performance evaluation of the old road surface and the design of the pavement maintenance scheme will determine the investment budget for the reconstruction of the old road network [1].Pavement performance evaluation is based on the collected pavement condition data to judge the degree of pavement performance to meet the requirements of use

Summary
By the end of 2017, the total mileage of expressways in China is close to 130,000 km, among which the service period of 5–10 years accounts for up to 45%. e performance evaluation of the old road surface and the design of the pavement maintenance scheme will determine the investment budget for the reconstruction of the old road network [1].Pavement performance evaluation is based on the collected pavement condition data to judge the degree of pavement performance to meet the requirements of use. Nunoo from Florida International University proposed to adopt the composite comprehensive evaluation algorithm to optimize the multiyear integrated pavement maintenance plan for the network pavement management and maintenance problems [10]. E shrinkage deformation of highway pavement in the semiarid climate area is prominent due to high temperature rutting in summer, low temperature cracking in winter, annual temperature difference, and diurnal temperature difference. Researchers began to apply fuzzy mathematics to highway performance evaluation index research. Li put forward a method of expressway asphalt pavement maintenance decision-making based on the matter-element model. Based on the above background, this paper relies on the reconstruction and expansion project of Xinglin section of the Taihang mountain expressway, and a method of highway pavement performance evaluation based on fuzzy mathematics is proposed. E types of pavement diseases are closely related to the temperature and precipitation in this area
