Energy and environment play a significant role in the quality of life, world s economic growth, and stability. China, USA, and many other countries encounter significant challenges related to energy saving and environmental concerns in the construction and maintenance of sustainable highway pavement, which is one of the biggest infrastructures in China and the United States. To address these challenges, a high level academic workshop was held in June 6-8, 2010 at Chang an University in Xi an, China. This workshop is sponsored by the National Natural Science Foundation of China (NSFC), National Science Foundation (NSF-USA), and National Science and Technology Supporting Program of China (2006BAJ18B05).
