Abstract:This technical memorandum documents the details and assumptions used to develop the University of California Pavement Research Center (UCPRC) life cycle inventory (LCI) database for quantifying the environmental impacts of California pavement projects, as well as some impacts from building heating, cooling, and lighting. The UCPRC LCI database presented in this technical memorandum is mainly the result of three UCPRC life cycle assessment studies: one completed for the California Air Resources Board and the California Department of Transportation (Caltrans) looking at the heat island effects of pavement, and two others for Caltrans that updated LCI for pavement processes. The LCI data presented were intended as background data for those studies and do not include foreground inventories for pavement designs, maintenance schedules, building designs, and vehicle traffic levels and fuel consumption. Further, the data in this technical memorandum do not include background information for any use stage elements other than building energy consumption (e.g., the LCI database presented in this report does not include pavement vehicle interaction, street lighting, carbonation, or albedo effects due to radiative forcing).
