Abstract

Unprecedented infrastructure construction, particularly in the transportation sector, has recently taken in China. This study estimated the material stock of transportation construction in China from 1993 to 2007. The results indicated that the steel, cement, and sand and gravel stocks of the railway system increased 1.5, 2.1 and 1.6 times, respectively, between 1993 and 2007, but the wood stock decreased. The steel and cement stocks of the highway system increased 18 and 2.8 times, respectively. Steel recycling is thus becoming an important factor for transportaion construction in China.
