INFRASTRUCTURE - Bridge abutment
The Geosynthetic Reinforced Soil (GRS) Integrated Bridge System (IBS) is a fast, cost-effective bridge support method, which combines the road with the superstructure to form a jointless interface between the bridge and the approach.
GRS: the alternative layer of compacted granular fill reinforced with geosynthetic reinforcement materials (such as geotextiles and geogrids).
The benefits of GRS abutments are:
It is more flexible than reinforced concrete or piled abutments.
It has high stability and extensibility under normal operation actions and extreme actions.
Reduce the possibility of sudden differential settlement during the transition from the approach embankment to the bridge abutment.
The cost is reduced, the construction rate is increased, and the requirements for construction equipment are reduced in cooperation with the pile-supported or ground-bearing reinforced concrete abutment.
