With recent advances made in post-tensioned segmental concrete bridge construction, we’re making significant strides toward achieving higher levels of sustainability in our projects as an industry. Specifically, new grouting material specifications and new approaches to grouting tendons, improvements in epoxy technology, innovation in post- tensioning systems, and new developments in concrete mix designs resulting in better, higher-strength concretes are improving our ability to get in, get out, and stay out. Read more…
