Efficient & Low-Impact Rehabilitation Using Precast Slabs
Webinar: Efficient and Low-Impact Rehabilitation Using Precast-Prestressed Concrete Replacement Slabs. Rapid construction, minimal impact to the public and low life cycle costs are quickly becoming common themes among Departments of Transportation across America. Precast Concrete Pavement replacement slabs have been successfully implemented in several states across the country and in fact, the technology has spread overseas to at least seven countries. Adding prestressing strand to the concrete slab increases the benefit this technology can provide to the designer. In this presentation, participants will be introduced to the uses and benefits of Precast Concrete Pavement replacement slabs with an emphasis on prestressing. Recent projects in Mobile, AL and Los Angeles, CA will be highlighted.
