In a groundbreaking interstate expansion project in Arizona, engineers harnessed recycled glass aggregate as a revolutionary structural fill. This eco-friendly innovation not only provided lightweight support for drainage culverts but also showcased impressive compressive strength. Utilizing foam glass from recycled bottles minimized the need for expensive culvert replacements and significantly cut down on construction delays, ultimately transforming waste into vital infrastructure enhancements.source https://timesofindia.indiatimes.com/world/us/in-2024-arizona-used-foam-made-from-100-recycled-glass-at-19-sites-while-widening-23-miles-of-i-17-the-lightweight-fill-helped-culverts-built-for-two-lanes-support-added-lanes/articleshow/133842120.cms
