GRS-IBS is a Federal Highway Administraon (FHWA) Every Day Counts Rounds 1 and 3 (EDC-1 and EDC-3) innovaon that Pennsylvania championed. What are the benefits? Reduces cost by up to 60 percent Easy to build and maintain Improves ride quality Decreases maintenance needed for selement repairs Extends the longevity of structures Easily modified design to adapt to field condions How does it work? GRS uses alternang layers of geotexle and compacted stone to create bridge substructure units. The integrated bridge system is created when the GRS is combined with beams and deck to strengthen the approach roadway. GRS-IBS permits bridges to be built in a faster and more cost-effecve manner that is also environmentally friendly. How do I learn more?

    Geosynthetic Reinforced Soil – Integrated Bridge Systems (GRSIBS)

    Reducing Bridge Construction Time Geosynthetic Reinforced Soil – Integrated Bridge Systems (GRSIBS), an Accelerated Bridge Construction (ABC) method, allows PennDOT and municipalities to build bridges quickly and cost effectively. They can be built using local workforce personnel and equipment to maximize efficiency. GRSIBS is a Federal Highway Administration (FHWA) Every Day Counts Rounds 1 and 3 (EDC1 and EDC3) innovation that Pennsylvania championed.

    What are the benefits? • Reduces cost by up to 60 percent

    • Easy to build and maintain

    • Improves ride quality

    • Decreases maintenance needed for settlement repairs

    • Extends the longevity of structures

    • Easily modified design to adapt to field conditions

    How does it work? GRS uses alternating layers of geotextile and compacted stone to create bridge substructure units. The integrated bridge system is created when the GRS is combined with beams and deck to strengthen the approach roadway. GRSIBS permits bridges to be built in a faster and more costeffective manner that is also environmentally friendly.
