. Environmental and economic assessment of pavement construction and management practices for enhancing pavement sustainability. Resources, Conservation and Recycling, Elsevier, 2017, 116, pp.15-31. 10.1016/j.resconrec.2016 WMA mixtures, reducing energy consumed and emissions generated in mixtures production, applying 7 in-place recycling techniques, and implementing preventive treatments. In this study, a comprehensive 8 and integrated pavement life cycle costing-life cycle assessment model was developed to investigate, 9 from a full life cycle perspective, the extent to which several pavement engineering solutions, namely 10 hot in-plant recycling mixtures, WMA, cold central plant recycling and preventive treatments, are 11 efficient in improving the environmental and economic dimensions of pavement infrastructure 12 sustainability, when applied either separately or in combination, in the construction and management 13 of a road pavement section located in Virginia, USA. Furthermore, in order to determine the preference 14 order of alternative scenarios, a multicriteria decision analysis method was applied. The results showed 15 that the implementation of a recycling-based maintenance and rehabilitation strategy where the asphalt 16 mixtures are of type hot-mix asphalt containing 30% RAP, best suits the multidimensional and 17 conflicting interests of decision-makers. This outcome was found to be robust even when different 18 design and performance scenarios of the mixtures and type of treatments are considered. 19 20
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.
