    Sponsors & Partners
  • Nebraska Department of Roads
  • Research Objective
    The objective of this research is to develop open and closed precast concrete bridge railing systems for use on cast-in-place and precast concrete bridge deck systems.
    Potential Benefits
    The successful development of a new family of precast rail systems will significantly reduce construction time and should ultimately reduce overall costs as contractors and precasters gain experience with the new system. Construction of precast bridge railing systems should be much less weather sensitive than cast-in-place bridge railing systems.
    Abstract
    For this research project, both open and closed precast concrete bridge railing system will be developed for use on a cast-in-place and precast concrete bridge deck systems. The two new railing systems will be designed to meet the Test Level 4 impact safety standards that are currently being revised in the update to NCHRP Report No. 350. The successful development of a new family of precast rail systems will significantly reduce construction time and should ultimately reduce overall costs as contractors and precasters gain experience with the new system. Construction of precast bridge railing systems should be much less weather sensitive than cast-in-place bridge railing systems.
