Abstract:In-place recycling is gaining more popularity as an end-of-life (EOL) treatment as it results in less consumption of virgin aggregates and less environmental impacts in hauling of materials to and from the site. However, there are challenges that needed to be addressed so that the benefits of in-place recycling can be objectively quantified, and the contexts in which recycling provides benefits compared to conventional options can be identified. This paper addresses this issue by defining a framework for comparison across all available alternatives by quantification of the impacts throughout the full life cycle of each option. The framework provides guidance on what parameters to considers, how to collect data, and how to create models at each life cycle stage for quantification of the impacts.
