Deployment of Sustainable Practices Using Lightweight Aggregates for Bridge Infrastructure
The state of bridge infrastructure in the United States has received a mediocre grade which indicates the vulnerable condition of these lifelines in response to extreme events as well as their poor serviceability during normal conditions. This assessment manifests challenges in the areas of condition, capacity, funding, and future needs, as well as innovation. Aging and structurally deficient bridges require prompt attention to enhance their performance and extend their service life. Presented case studies discuss opportunities to achieve these objectives for existing and new bridges through the application of sustainable practices for both superstructure and substructure components. The key focus in these opportunities is the application of rotary-kiln manufactured lightweight aggregates. These applications cover a wide range of techniques to (1) enhance the service life of bride decks, (2) improve the capacity of the superstructure, and (3) reduce demands on the abutment walls, all contributing to the resilience of bridge infrastructure and their performance during extreme events. Further discussions include ratings and assessment of various practices and their interdependencies with the infrastructure resilience measures, as well as environmental and social resilience, and sustainability objectives.
