废旧轮胎在国内外道路工程中的应用现状

State of the Art about Application of Waste Tire in Road Engineering in China and Abroad

汽车工业的发展和汽车数量的增加,在给人民生活带来方便的同时,也产生了大量的废旧轮胎。废旧轮胎的堆积和不当处理,将对生态环境带来严重的污染,国内外学者对废旧轮胎的综合利用开展了大量的研究,将废旧轮胎经粉碎等处理制成橡胶沥青,应用于道路工程不仅提高了道路的耐热等性能,而且减少了生态环境污染,具有良好的社会效益、经济效益和环境效益。本文介绍了国内外对废旧轮胎在道路工程中的应用情况,通过与国外研究和工程实践的对比,指出了我国在此方面研究中存在的问题,为进一步废旧轮胎在道路工程中综合利用提供指导作用。

With the development of automobile industry and increment of mobile numbers, humans are more convenient to travel anywhere. However, the storage and inappropriate disposing of mobile generated waste tire brings a huge pressure to the ecological environment. In order to consume this harmful solid waste, scholars and engineers all over the world carried out a lot of researches on the usage of these waste tires. The waste tire are broken into rubber powder and mixed into asphalt. The rubber asphalt is then used to road engineering, which is benefit not only on high temperature stability but also on environment protection, and thus beneficial to the society, economy and environment. This paper introduced the application of waste tire in road construction in China and abroad. The limitations of researches and applications of China in this field was point out to provide reference suggestions for the usage of waste tire in road construction.
