41	Integrating steel slag aggregates into asphalt paving by harmonizing availability, quality, economics, and the environment Murphy, Timothy R. 12 May 2023 (has links) (PDF) This thesis provides guidance on how to balance matters related to the environmental stewardship, market sources, origin and uses, material properties, performance, and economic impact of using slag materials in pavements. The literature on this topic provides numerous references on the use of slag materials for specific applications, and this thesis aims to make use of those references along with other data from the author to describe slag materials from a holistic perspective and provide some suggestions for balancing several factors that impact optimal use of this resource within pavement structures. Discussion is given to the increased importance of recycling of other materials into the infrastructure and benchmarking those materials against recycling of steel slag. Ensuring adequate performance of pavements while increasing the use of recycled materials and maintaining safety is a successful measure relative to green initiatives and occurs only with careful planning, cooperation, and field validations. steel slag recycling environmental recycled asphalt construction economics sustainability Civil Engineering Construction Engineering and Management Environmental Engineering Materials Science and Engineering Other Engineering Science and Materials Risk Analysis
