This study utilizes and enhances the Caltrans’ pavement management system (PaveM) to evaluate and quantify GHG emissions attributed to pavements of the State Highway System (SHS) over the next 30 years in the two major stages of materials and Construction activities (M&C Stage) and vehicles operation (Use Stage) influenced by rolling resistance. This study also utilizes GIS technology in mapping transportation-related GHG emissions quantities in both stages.
