Asphalt Rubber and Its Potential Use in China
In 2004, the number of scrap tires in China reached 120 millions and this number is increasing by 12% every year. There is a considerable demand for using scrap tires in civil engineering applications. This paper presents a description of asphalt rubber technology and its potential use in China as an alternative use for scrap tires. Asphalt rubber has been used in the United States of America and several other countries for many years and the asphalt rubber products have been shown to provide significantly improved engineering properties over conventional paving grade asphalt. Consequently, pavements constructed with asphalt rubber mixes have many benefits such as improved durability and improved resistance to surface initiated fatigue and reflection cracking, improved aging and oxidation resistance due to higher binder contents, thicker binder films, and anti-oxidants in the tire rubber. The use of asphalt rubber is not only an innovative way to recycle used tires that otherwise would be wasted, but also one of the most effective methods in extending pavement life through the improved engineering properties of the asphalt rubber products. China has thousands of miles of semi-rigid asphalt concrete and portland cement concrete pavements in need of maintenance and rehabilitation. This paper presents the latest advances in the asphalt rubber technology and the state-of-the-practice and discusses various asphalt rubber products used by the California Department of Transportation and their potential use in China.
