摘要:   Environmental issues are becoming increasingly important in the domestic, business and public sectors.Due to population growth and growing number of megacities, Green Public Procurements concepts is also becoming an increasing trend in the road infrastructure sector.This study assessed the environmental impacts of road markings considering the whole life cycle from manufacturing to disposal.For the accuracy of the study, an external expert panel has reviewed the assessment.By using the LCC-(based on DIN EN 60300) and LCA-Methodology (based on ISO 14040 and following), an objective comparison for the following sprayed line markings was performed: Solvent-borne paint;Water-based paint;Thermoplastic and Thermo Spray Plastic;MMA Cold Plastic and MMA Cold Spray Plastic.Typical material formulations in characteristic application scenarios have been modelled using the data of corresponding official approval test certificates held by a major local manufacturer of all evaluated technologies.Empirical data was used to determine a typical service life of the various road marking systems at a typical average daily traffic of 10 000-15 000 vehicles per day.The life cycle assessment results, i.e.considering the whole life cycle from manufacturing to disposal, show that a global warming potential reduction of more than 50% can be achieved with a more durable road marking system.The study concluded that in order to access the actual environmental impact of road markings, a lifetime evaluation including, for instance, production, application, transport, service life, and disposal must be taken into consideration.
