[Abstract]:Freezing condition has great influence on the skid resistance of asphalt pavement. It is very important to study the anti-skid performance of asphalt pavement under freezing condition. However, a great deal of research on the anti-skid of pavement is limited to the asphalt pavement under the conventional non-frozen condition, and the research on the anti-skid characteristic of the asphalt pavement under the frozen condition is obviously insufficient. Moreover, there is a lack of uniform testing method of asphalt pavement friction performance and evaluation index and standard of mature system under freezing condition. Therefore, it is necessary to study the evaluation method of asphalt pavement's skid resistance under freezing condition. In view of the above problems, this paper developed a test equipment to simulate the skid resistance of asphalt pavement under freezing condition, and carried out the research on the variation law of anti-skid characteristic of asphalt pavement under freezing condition. On the basis of analyzing the influence significance and interaction of the influencing factors of asphalt pavement under freezing condition, the evaluation index and standard of asphalt pavement anti-slide characteristic considering freezing condition are discussed. The main research contents are summarized as follows: (1) aiming at the lack of equipment for measuring the friction performance of asphalt pavement under frozen conditions in China, a tribological performance tester which can measure the friction performance of asphalt pavement in frozen environment is developed, which is based on the principle of measurement system analysis. The accuracy, reliability and stability of the data measured by the newly developed instrument are verified, and the calibration of the instrument is completed. (2) based on different types of asphalt pavement, the testing equipment such as friction performance tester and dynamic friction tester are used. Under the conditions of different freezing environment, different vehicle simulation parameters and other factors, the friction characteristics of asphalt pavement under freezing condition are studied, and the results show that under different freezing conditions, road surface conditions and vehicle conditions, (3) based on the orthogonal design and analysis theory, the sensitivity of the factors affecting the friction characteristics of asphalt pavement under different freezing conditions and the interaction between them are analyzed. The main factors affecting the evaluation of the anti-slide characteristics of asphalt pavement under frozen conditions are expounded. (4) based on the PIARC pavement anti-slide evaluation model, the feasibility of applying the model to the evaluation of anti-skid characteristics of asphalt pavement under frozen conditions is discussed. Based on the current evaluation index and classification standard of asphalt pavement in China, this paper discusses the classification standard of asphalt pavement anti-skid property under freezing condition. In this paper, the evaluation method of anti-skid characteristics of asphalt pavement under freezing condition provides the basic equipment and basic basis for the study of anti-skid problem under frozen condition, and also provides a good impetus and reference for further research.
