Abstract: Toward the goals of green, low-carbon construction and maintenance, as well as sustainable development of transportation infrastructure, this paper quantitatively analyzed the list of environmental loads of the preparation of rubber powder by recycling waste tires based on the life cycle assessment methodology. The environmental impact assessment for the production of raw materials, mixing and transportation as well as pavement construction was further conducted. Results show that the environment impact of the crumb rubber asphalt paving can be significantly increased by considering the environmental load from the waste tires itself by treating them as a resource. Special focus should be placed on the greenhouse effect caused from the paving of rubber asphalt and the environmental load during the production phase of the raw materials.
