【摘要】：冰冻条件对沥青路面的抗滑性能带来重大影响,冰冻条件下沥青路面的抗滑性能研究非常重要。但国内外对路面抗滑做的大量研究都局限于常规非冰冻条件下的沥青路面,冰冻条件下沥青路面的抗滑特性研究明显不足,而且缺少标准统一的冰冻条件下沥青路面摩擦性能检测方法和成熟系统的评价指标与标准。因此,开展冰冻条件下沥青路面的抗滑特性评价方法的研究十分必要。针对上述问题,本文开发了模拟冰冻条件下沥青路面抗滑特性的试验设备;开展了冰冻条件下沥青路面抗滑特性变化规律的研究;分析了冰冻条件下沥青路面影响因素的影响显著性和交互作用;在此基础上,探讨了考虑冰冻条件的沥青路面抗滑特性评价指标和标准。主要研究内容概括如下:(1)针对国内对冰冻条件下沥青路面摩擦性能测量设备欠缺问题,开发了能在冰冻环境下测量路面摩擦性能的摩擦性能试验机;基于测量系统分析原理,验证了新开发仪器所测量数据准确性、可靠性和稳定性,完成了对仪器的标定。(2)采用摩擦性能试验机和动态摩擦测试仪等试验设备,基于不同的沥青路面类型、不同的冰冻环境、不同车辆模拟参数等因素变量下,开展了冰冻条件下沥青路面的摩擦特性试验研究,得到了在不同冰冻条件、路面条件和车辆条件下,沥青路表摩擦性能的变化规律。(3)依托正交试验设计和分析理论,分析了各冰冻条件下沥青路面摩擦特性影响因素的敏感性以及各因素间的交互作用,阐明了在评价冰冻条件下沥青路面抗滑特性时,主要考虑的影响因素。(4)基于PIARC路面抗滑评价模型,探讨了该模型运用于冰冻条件下沥青路面抗滑特性评价上的可行性;基于我国路面现行的沥青路面抗滑评价指标和分级标准,探讨了冰冻条件下沥青路面抗滑特性评价的分级标准。本文对冰冻条件下沥青路面的抗滑特性评价方法,为冰冻条件下的抗滑问题研究提供了基础设备和基本依据,也为后续的研究提供很好的推动和借鉴作用。
[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.
