Emission intensity of polymer modified bitumen (PMB). Bitumen with 3.5% SBS polymer. Polymer modified bitumen has a higher embodied carbon due to the higher impact of the polymer. However the use of a polymer in asphalt mixtures is considered to increase the road lifetime. There wasn't sufficient evidence to place the additional lifetime in numbers. Further research would be needed. PMB is therefore best judged on a whole life basis. Source: Eurobitume 2012. Life cycle inventory bitumen 2nd edition Published by the European Bitumen Association. The value covers the embodied carbon excluding embodied carbon from infrastructure (i.e. carbon to make machines that make machines or embodied carbon of buildings). GWP factors from IPPC AR5 applied without carbon feedback.
