چکیده مقاله
Abstract Modern civil engineering projects put more emphasis on sustainable and environmentally friendly construction Concrete pavements contribute a considerable amount of carbon dioxide CO2 to the atmosphere due to the use of Portland cement Among different kinds of concrete pavement, Roller Compacted Concrete Pavement RCCP is a durable, economical, and eco friendly type of concrete pavement However, mass production of RCCP for infrastructure development may lead to a large amount of CO2 emissions Therefore, it is very vital to identify a substitution for the cement to make a more cost effective and environmentally friendly RCCP In this study, the possibility of using fly ash FA and ground granulated blast furnace slag GGBFS as cement replacement in RCCP is investigated The use of FA and GGBFS in RCCP mixtures reduced the global warming potential GWP up to around 40% Also, the use of FA and GGBFS in RCCP have had a great effect on compressive strength, water absorption anddensity Therefore, it can be concluded that durable and eco friendly RCCP with suitable hardened state properties with low CO2 production could be produced by incorporating FA and GGBFS as a cement replacement by 45% and 30%, respectively
