The MIT Concrete Sustainability Hub (CSHub) is conducting life cycle environmental and cost analyses of pavements under a wide range of contexts. The analyses involve the comparison of new asphalt concrete (AC) and portland cement concrete (PCC) pavement designs for a series of defined scenarios. The CSHub commissioned Applied Research Associates (ARA) to create these pavement designs. This section defines the scope of the scenarios and the guidelines set forth in creating the designs. The purpose of this document is to assemble all supporting information for the LCA and LCCAs, including designs, maintenance and repair, and cost data. Results for the scenario analysis will be published on the CSHub website as they become available.
