Reinforced earth bridge abutment method
The RRR method (Reinforced Railroad with Rigid Facing-Method) is a new soil retention (reinforced soil wall) technique developed as an alternative to traditional retaining wall methods, using the principles of reinforced soil engineering. Traditional retaining walls are structures that, from a mechanical perspective, aim to support external forces (earth pressure) exerted by the soil through the weight of the structure and the ground reaction of the foundation, opposing the soil and relying on force to counteract force. In contrast, the reinforced soil wall method promotes the stabilization of the soil itself by placing tensile reinforcement materials within the soil, embodying a philosophy of coexistence with the soil.

basic information
【Features】 ○ By connecting, the stability of the bridge abutment is dramatically improved, and the oscillation and settlement can be significantly reduced. ○ By using cement-improved soil to support the bridge abutment structure with multi-layer geotextile reinforcement, the generated sectional forces are reduced, resulting in a significantly slimmer structure and footing compared to conventional bridge abutments. ○ It was developed with the aim of dramatically increasing the rigidity of the reinforced embankment through preload and prestressing, making it applicable to structures that bear larger loads (such as bridge abutments, piers, and foundations of important structures). ● For more details, please contact us or download the catalog.

Company information
The RRR Method Association was established in July 1991 with the aim of promoting and improving the technology of reinforced soil methods that effectively utilize the effects of planar reinforcement materials or rod-shaped reinforcement materials and rigid wall surfaces to provide rational and highly stable soil structures. At its inception, the association started with a total of 63 regular and associate members and has since actively worked towards the dissemination and technological advancement of the RRR method. As of June 2008, 17 years after the establishment of the association, it has developed into an organization with a proven track record of over 100 km in reinforced soil retaining walls in the fields of railways and roads. This achievement is entirely thanks to the support and cooperation of everyone involved, for which we express our heartfelt gratitude.
