Green Road Construction Technologies in Guangzhou

Abstract

Total road pavement in Guangzhou reaches 77 ×10⁶ m². 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 promotion, 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.
