Can access openings for maintenance and/or fire rescue be provided for precast concrete noise barriers?
Yes, secured doors and frames or access hatches can easily be incorporated into the design of a precast concrete noise barrier. Blockouts for access to fire hydrants may also be cast in or can be cored in the field. Barriers may also be designed with an overlap, providing a larger opening for maintenance crews and/or emergency vehicles to access the roadway. A properly designed overlap will ensure the wall’s performance is not compromised.
