A Federal Highway Administration (FHWA) YouTube video showcases the history and construction techniques of the geosynthetic reinforced soil–integrated bridge system (GRS–IBS).
The video illustrates how to build a GRS–IBS. It is intended to educate designers, engineers, contractors and inspectors on the fundamentals of the GRS–IBS. The video follows the GRS–IBS Interim Implementation Guide (FHWA-HRT-11-026).
The 19-minute video includes:
- Explanation of GRS–IBS and its history of development
- Interviews with designers, owners and construction personnel
- Narrated video footage to explain the construction of the three main components (reinforced soil foundation, abutment and integrated approach)
- Time lapse photography to show the speed of construction
