Why a GRS Abutment?
•
Simple to design
•
Simple to build
•
CHEAP
•
No bump at the end of the road/bridge
•
And again, inexpensive and simple to build
What is GRS/IBS
•
A system of stacked
concrete blocks
for a wall facing
•
The fill behind the wall is composed of gravel interlaid with geotextile
fabric
•
The bridge deck sits on the compacted gravel mass and not on the
wall itself
•
These can be built quickly
•
Only a few hands track hoe are need to build a bridge
•
There is little or no maintenance needed
•
No settlement at the end of the bridge
Abutment and Deck Detail
Fine print Details:
Basically, it is a gravity structure with 12” layers
The ‘burrito’ detail for the base and layers for
the mass abutment
The deck sits on the compacted gravel mass

GRS/IBS system utilizes stacked concrete blocks for wall facing, with gravel and geotextile fill supporting the bridge deck. These abutments are easy to design and build, cost-effective, and require minimal maintenance. The unique design prevents settlement at the end of the bridge, offering a durable solution with quick construction.
