Carbon Footprint: How does asphalt stack up?

In terms of environmental sustainability, this publication seeks to answer the question, how do you measure the greenness of a pavement? An analysis of both asphalt and concrete pavements is presented in this white paper, using a variety of methodologies. Initial construction as well as a 50-year life-cycle were analyzed. The carbon footprints of the asphalt pavements were found to be less than 30 percent of equivalent Portland cement concrete pavements in all cases. Although the carbon footprint of the initial construction of a Perpetual Pavement (one that is designed for longer life) was found to be slightly higher than that associated with conventional asphalt pavement in one of the analyses, the Perpetual Pavement had a lower 50-year lifetime carbon footprint.
