Abstract
This paper presents a case study of the restoration of village road located between Zone 2A and Zone 2B after the excavation for box culvert underneath it. Geotechnical investigations showed that the area will be constructed upon volcanic rock material. The height of the Geoframe is approximately 19.7 meters. This system is a combination of polyester strip for reinforcing element and connected with clamp to the facing made of galvanized steel as a permanent formwork and non-woven geotextile material for filter element. The inclination of Geoframe structure can reach almost vertical with over 85⁰ inclined facing. The result of this work, Geoframe’s facing can be grown with vegetation (grass) to accentuate a natural and green structure. From design perspective, the embankment safety factor was above the criteria stated in Indonesian National Standard for Geotechnical Design Requirements which is above 1.50 and design with pseudo-static earthquake load which is above 1.10. The system has proven to be easy to implement in the field, fast and can be carried out with good quality control.
