A technical survey on mechanism and influence factors for asphalt pavement skid-resistance

Friction 2024年第5期12卷 845-868页

作者： Xiyin LIU Haoyuan LUO Can CHEN Leyi ZHU Siyu CHEN tao ma Xiaoming HUANG School of Transportation Southeast UniversityNanjing211189China

To explore the research status on mechanism of the skid-resistance for asphalt pavement, the related achievements of the rubber friction, the tire–road contact, and the influence factors were reviewed. The rubber friction was reviewed from the mechanism and rubber friction model. The tire-road contact was studied from the modeling methods, the evaluation methods, and the skid-resistance mechanisms at different conditions. The influence factors of skid-resistance were summarized from different designing processes. This review showed that the appropriate contact or evaluation model should be selected according to the required parameters. Although the finite element method is widely used, the accuracy of the model, the boundary conditions, and the load cases need to be further improved. The optimized aggregates and asphalt binders, reasonable gradation, reasonable geometric design, and strict construction quality control are necessary for good initial skid-resistance. Pavement texture as an important factor affecting skid-resistance should be considered in pavement gradation design, especially for wearing layer technology.

中国是诗的国度,文学在中华五千年的民族精神传承中发挥了至关重要的作用,从“诗言志”到“诗缘情”,文学在人们外在的社会生活和内在的精神追求中始终在场,形成了我们民族的文化底色。文学之所以在我们的文化中扮演着如此重要的角色,与汉字作为表意文字的象征意味密不可分,汉字所建构的文学世界是我们精神的自然外化和延伸。当代文学和文艺理论成长于日新月异的现代生活,但其特色仍然源于我们的文学传统。习近平总书记在文化传承发展座谈会上指出:“在五千多年中华文明深厚基础上开辟和发展中国特色社会主义,把马克思主义基本原理同中国具体实际、同中华优秀传统文化相结合是必由之路。”①“两个结合”深刻阐明了文艺理论生发的现实语境与历史源头,当代文艺理论的建构与发展,应当以“两个结合”为指引,在历史与现实的交汇处进行理论创新。

18-19世纪前期是英国工业化的重要时期,与工业化相伴的是煤炭产业的大发展,并在此基础上形成了伦敦煤炭市场和内地煤炭市场。受交通、垄断组织等因素影响,伦敦煤市和内地煤市各有其独立的煤价生成机制。在伦敦煤市,煤价主要受到垄断组织的操控;在内地煤市,煤价则更多受交通因素的影响。当时英国的煤价体系实际上是伦敦煤价与内地煤价并存的煤价体系。伦敦煤价生成机制在保障伦敦能源供给的同时加剧了伦敦煤市的封闭性,导致内地煤难以进入伦敦煤市,只能寻求就地消化,也让长期享受高煤价红利的东北部忽视本地工业建设,因而经济逐渐衰落;内地煤价生成机制却触发了英国内陆交通大变革,引发煤炭产业地理格局的重构,在低煤价区孕育出以运河为依托的发达工业区。英国工业地理格局由此发生变化,地处煤价洼地的英格兰西北部开始崛起,成为英国工业化最快的地区,并对英国工业经济的崛起产生影响。
