Construction industry similarly to any other industry, is forced to face recent trends and necessary environmentally friendly solutions, like for example emphasizing emission reduction. On the other hand, modern methods, especially coming from the IT sector, are often not easy adoptable for this industrial area. As part of ongoing research activities started within the European CoRePaSol project and continuously followed in Centre for Effective and Sustainable Transport Infrastructure in the Czech Republic to focus was oriented on the issue of energy demand and emission production calculation for pavement recycling techniques. Together with these assessments a new software tool was developed, which is in detail oriented on the determination of environmental burden in terms of emissions if different pavement rehabilitation techniques are used. There were already lots of studies on greenhouse gas emissions presented, but most of them focus mainly on CO2, not reflecting other emissions. The importance of this paper is in the detailed identification and understanding and description of other greenhouse gas emissions like NOx, HC, CO, fine particles matter and also CO2. The study contains an application of the assessment software (calculator) for a real job site, presenting possible pavement rehabilitation methods including their technological variants and a subsequent decision for a preferred solution. Included are traditional rehabilitation methods (mill&fill, including RAP material with different portion) as well as both cold and hot in-place recycling techniques. This paper aims to show the truth of environmental impact of available rehabilitation methods, as well as to present the developed software application.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
