This project aims to review the current literature on practices, reports, and manuals to outline existing safety technologies and analyze the effectiveness of the proposed procedure and strategies implemented in work zones by states.
The manufacturing of Portland cement leads to notable greenhouse gas (GHG) emissions, which has driven interest in alternative concrete mixture designs, cement production processes, and other emissions mitigation strategies. To demonstrate the efficacy of such mitigation strategies, environmental impact assessments are commonly performed. However, examination of the probability that a reduction in GHG emissions will occur given known limitations on data quality and variability in data remains poorly studied.
Through development of necessary benchmarks as well as robust tools for assessment and improvement, this work will better inform the procurement of concrete for transportation infrastructure. Further, the tools developed will quantify potential co-benefits or unintended consequences to other environmental impacts.
This white paper summarizes the state-of-knowledge and state-of-the-art in pavement life cycle assessment modeling, with particular emphasis on life cycle greenhouse gas emissions and on interpretation and analysis that lead to GHG reductions from the on-road transportation sector.
