This workshop brought together a diverse group of stakeholders to exchange and discuss unanswered questions and to discuss a proposed road map to fill the gaps in knowledge regarding permeable pavement.
This research brief summarizes the associated project, which developed a methodology that combines urban metabolism and life cycle assessment to examine the life cycle impacts of hardscapes at the urban scale rather than at the product or project scale.
Researchers surveyed all 50 state departments of transportation and conducted in-depth interviews with agency experts to understand the implementation status of complete streets asset management, identify what state transportation agencies need to improve their asset management plans, and develop a road map for implementing complete streets asset management.
This policy brief summarizes findings and provides policy implications from research that analyzed life cycle assessment literature to understand whether alkali-activated materials can achieve the same mechanical performance as Portland cement with lower CO2 emissions.
To increase the adoption of Alkali activated materials concrete for civil applications such as pavements, it is fundamental to analyze the existing literature to clarify the link between environmental and mechanical performance, identifying opportunities for applications that are tailored to the local availability of raw material, reducing transport environmental costs.
