Proper Manufacturing and Installation of Precast Box Culverts

Class Description: State DOTs and local agencies are faced with significant challenges in addressing the needs of their roadways and bridges. More than 25 percent of the Nation’s 600,000 bridges are rated as structurally deficient or functionally obsolete. More than 30 percent of existing bridges are over 50 years old and are in need of various levels of repairs, rehabilitation, or replacement. Precast Box Culverts provide creative and economic options for replacing bridges that ensure the resilience of our nation’s infrastructure. Precast Box Culverts (RCB) empower owners with a time saving, extremely durable bridge-replacement option. Replacing an aging bridge in a few days versus several weeks reduces road user impacts, improves work zone safety and saves money for another project. This class highlights how precast box culverts are manufactured and installed. It also raises our awareness on creative DOT practices and recent innovations related to precast box culverts. This lively workshop will change the way you think about installing box culverts. You will learn about compaction, excavation steps, bedding placement, joining box culverts, and backfilling procedures. You will learn common crew tasks implemented during the installation and inspection of precast box culverts.
