Green Road Construction Technologies in Guangzhou

Total road pavement in Guangzhou reaches 77 10 6 m 2 . Its huge maintenance and potential rehabilitation calls for a green road system. This paper presents a discussion, first about green road construction technologies together with their applications and development like reclaimed asphalt pavement, rubberized asphalt pavement, and warm mix asphalt; and then, about the key obstacles for promotion and activities, primarily for green road promo- tion, in the perspectives of the current technical and application situations in China and separately in Guangzhou. Based on environmental and conditional analysis, as well as a development expectation from an industrial viewpoint, this paper creates a development trend of green road technologies.
